The "_get_comp_words_by_ref -n := words" command from the
bash_completion library reassembles a modified version of COMP_WORDS
with ':' and '=' no longer treated as word separators and stores it in
the ${words[@]} array. Git's programmable tab completion script uses
this to abstract away the difference between bash v3's and bash v4's
definitions of COMP_WORDS (bash v3 used shell words, while bash v4
breaks at separator characters); see v1.7.4-rc0~11^2~2 (bash: get
--pretty=m<tab> completion to work with bash v4, 2010-12-02).
zsh has (or rather its completion functions have) another idea about
what ${words[@]} should contain: the array is prepopulated with the
words from the command it is completing. For reasons that are not
well understood, when git-completion.bash reserves its own "words"
variable with "local words", the variable becomes empty and cannot be
changed from then on. So the completion script neglects the arguments
it has seen, and words complete like git subcommand names. For
example, typing "git log origi<TAB>" gives no completions because
there are no "git origi..." commands.
However, when this words variable is not declared as local but is just
populated by _get_comp_words_by_ref() and then read in various
completion functions, then zsh seems to be happy about it and our
completion script works as expected.
So, to get our completion script working again under zsh and to
prevent the words variable from leaking into the shell environment
under bash, we will only declare words as local when using bash.

In v1.7.4-rc0~11^2~2 (bash: get --pretty=m<tab> completion to work
with bash v4, 2010-12-02) we started to use _get_comp_words_by_ref()
to access completion-related variables. That was large change, and to
make it easily reviewable, we invoked _get_comp_words_by_ref() in each
completion function and systematically replaced every occurance of
bash's completion-related variables ($COMP_WORDS and $COMP_CWORD) with
variables set by _get_comp_words_by_ref().
This has the downside that _get_comp_words_by_ref() is invoked several
times during a single completion. The worst offender is perhaps 'git
log mas<TAB>': during the completion of 'master'
_get_comp_words_by_ref() is invoked no less than six times.
However, the variables $prev, $cword, and $words provided by
_get_comp_words_by_ref() are not modified in any of the completion
functions, and the previous commit ensures that the $cur variable is
not modified as well. This makes it possible to invoke
_get_comp_words_by_ref() to get those variables only once in our
toplevel completion functions _git() and _gitk(), and all other
completion functions will inherit them.

Since v1.7.4-rc0~11^2~2 (bash: get --pretty=m<tab> completion to work
with bash v4, 2010-12-02) we use _get_comp_words_by_ref() to access
completion-related variables, and the $cur variable holds the word
containing the current cursor position in all completion functions.
This $cur variable is left unchanged in most completion functions;
there are only four functions modifying its value, namely __gitcomp(),
__git_complete_revlist_file(), __git_complete_remote_or_refspec(), and
_git_config().
If this variable were never modified, then it would allow us a nice
optimisation and cleanup. Therefore, this patch assigns $cur to an
other local variable and uses that for later modifications in those
four functions.

Commit a8f3e2219 introduced the strbuf_grow() call to strbuf_setlen() to
make ensure that there was at least one byte available to write the
mandatory trailing NUL, even for previously unallocated strbufs.
Then b315c5c0 added strbuf_slopbuf for the same reason, only globally for
all uses of strbufs.
Thus the strbuf_grow() call can be removed now. This avoids readers of
strbuf.h from mistakenly thinking that strbuf_setlen() can be used to
extend a strbuf.
The following assert() needs to be changed to cope with the fact that
sb->alloc can now be zero, which is OK as long as len is also zero. As
suggested by Junio, use the chance to convert it to a die() with a short
explanatory message. The pattern of 'die("BUG: ...")' is already used in
strbuf.c.
This was the only assert() in strbuf.[ch], so assert.h doesn't have to be
included anymore either.

If somebody has a name that includes an rfc822 special, we
will output it literally in the "From:" header. This is
usually OK, but certain characters (like ".") are supposed
to be enclosed in double-quotes in a mail header.
In practice, whether this matters may depend on your MUA.
Some MUAs will happily take in:
From: Foo B. Bar <author@example.com>
without quotes, and properly quote the "." when they send
the actual mail. Others may not, or may screw up harder
things like:
From: Foo "The Baz" Bar <author@example.com>
For example, mutt will strip the quotes, thinking they are
actual syntactic rfc822 quotes.
So let's quote properly, and then (if necessary) we still
apply rfc2047 encoding on top of that, which should make all
MUAs happy.

For projects that do not release official archives, gitweb's snapshot
feature would be an excellent alternative, and but without the '-n'
('--no-name') argument, gzip includes a timestamp in output which results
in different files. Because some systems hash/checksum downloaded files
to ensure integrity of the tarball (e.g FreeBSD), it is desirable to
produce tarballs in a reproducible way for that purpose.
Whilst '--no-name' is more descriptive, the long version of the flag is
not supported on all systems. In particular, OpenBSD does not appear to
support it.
Supply '-n' to gzip to exclude timestamp from output and produce idential
output every time.

* js/maint-1.6.6-send-pack-stateless-rpc-deadlock-fix:
send-pack: avoid deadlock when pack-object dies early
Evil merge to adjust the way the use of pthreads in sideband-demultiplexor
was decided (earlier it was "if we are not on Windows", now it is "if we
are not using pthreads").
Send-pack deadlocks in two ways when pack-object dies early (for example,
because there is some repo corruption).
The first deadlock happens with the smart push protocol (--stateless-rpc).
After the initial rev-exchange, the remote is waiting for the pack data
to arrive, and the sideband demuxer at the local side continues trying to
stream data from the remote repository until it gets EOF. Meanwhile,
send-pack (in function pack_objects()) has noticed that pack-objects did
not produce output and died. Back in send_pack(), it now tries to clean
up the sideband demuxer using finish_async(). The demuxer, however, waits
for the remote end to close down, the remote waits for pack data, and
the reason that it still waits is that send-pack forgot to close the
outgoing channel. Add the missing close() in pack_objects().
The second deadlock happens in a similar constellation when the sideband
demuxer runs in a forked process (rather than in a thread). Again, the
remote end waits for pack data to arrive, the sideband demuxer waits for
the remote to shut down, and send-pack (in the regular clean-up) waits for
the demuxer to terminate. This time, the send-pack parent process closes
the writable end of the outgoing channel (in start_command() that spawned
pack-objects) so that after the death of the pack-objects process all
writable ends should have been closed and the remote repo should see EOF.
This does not happen, however, because when the sideband demuxer was forked
earlier, it also inherited a writable end; it remains open and keeps the
remote repo from seeing EOF. To break this deadlock, close the writable end
in the demuxer.

"git add -u" updates the index with the updated contents from the working
tree by internally running "diff-files" to grab the set of paths that are
different from the index. Then it updates the index entries for the paths
that are modified in the working tree, and deletes the index entries for
the paths that are deleted in the working tree.
It ignored the output from the diff-files that indicated that a path is
unmerged. For these paths, it instead relied on the fact that an unmerged
path is followed by the result of comparison between stage #2 (ours) and
the working tree, and used that to update or delete such a path when it is
used to record the resolution of a conflict.
As the result, when a path did not have stage #2 (e.g. "we deleted while
the other side added"), these unmerged stages were left behind, instead of
recording what the user resolved in the working tree.
Since we recently fixed "diff-files" to indicate if the corresponding path
exists on the working tree for an unmerged path, we do not have to rely on
the comparison with stage #2 anymore. We can instead tell the diff-files
not to compare with higher stages, and use the unmerged output to update
the index to reflect the state of the working tree.
The changes to the test vector in t2200 illustrates the nature of the bug
and the fix. The test expected stage #1 and #3 entries be left behind,
but it was codifying the buggy behaviour.

2. pseudo-options that must be parsed in order with their revision

The global options are taken care of by handle_revision_opt; the
pseudo-options are currently in a deeply indented portion of
setup_revisions. Give them their own function for easier reading.

When relative dates are more than about a year ago, we start
writing them as "Y years, M months". At the point where we
calculate Y and M, we have the time delta specified as a
number of days. We calculate these integers as:
Y = days / 365
M = (days % 365 + 15) / 30
This rounds days in the latter half of a month up to the
nearest month, so that day 16 is "1 month" (or day 381 is "1
year, 1 month").
We don't round the year at all, though, meaning we can end
up with "1 year, 12 months", which is silly; it should just
be "2 years".
Implement this differently with months of size
onemonth = 365/12
so that
totalmonths = (long)( (days + onemonth/2)/onemonth )
years = totalmonths / 12
months = totalmonths % 12
In order to do this without floats, we write the first formula as
totalmonths = (days*12*2 + 365) / (365*2)

If start_command fails after forking and before exec finishes, there
is not much use in noticing an I/O error on top of that.
finish_command will notice that the child exited with nonzero status
anyway. So as noted in v1.7.0.3~20^2 (run-command.c: fix build
warnings on Ubuntu, 2010-01-30) and v1.7.5-rc0~29^2 (2011-03-16), it
is safe to ignore errors from write in this codepath.
Even so, the result from write contains useful information: it tells
us if the write was cancelled by a signal (EINTR) or was only
partially completed (e.g., when writing to an almost-full pipe).
Let's use write_in_full to loop until the desired number of bytes have
been written (still ignoring errors if that fails).
As a happy side effect, the assignment to a dummy variable to appease
gcc -D_FORTIFY_SOURCE is no longer needed. xwrite and write_in_full
check the return value from write(2).

Add some tests to make sure it doesn't happen again.
The hello-script used in these tests uses cat instead of echo because
on Windows the bash spawned by git converts LF to CRLF in text written
by echo while the bash running tests does not, causing the test to
fail if "echo" is used. Thanks to Hannes for noticing.
