Corrected the log starting time displayed in the error message
(as it was always showing the epoch due to a bad input to strtoul).
Improved the log parser so we only scan backwards towards the
'\n' from the end of the prior log; during this scan the last '>'
is remembered to improve performance (rather than scanning forward
to it).
If the log record matched is the last log record in the file only
use its new sha1 value if the date matches exactly; otherwise we
leave the passed in sha1 alone as it already contains the current
value of the ref. This way lookups of dates later than the log
end to stick with the current ref value in case the ref was updated
without logging.
If it looks like someone changed the ref without logging it and we
are going to return the sha1 which should have been valid during
the missing period then warn the user that there might be log data
missing and thus their query result may not be accurate. The check
isn't perfect as its just based on comparing the old and new sha1
values between the two log records but its better than not checking
at all.

Install git-send-email by default
Fix compilation on newer NetBSD systems
git config syntax updates
Another config file parsing fix.
checkout: use --aggressive when running a 3-way merge (-m).
This updates the hierarchical section name syntax to
[section<space>+"<randomstring>"]
where the only rule for "randomstring" is that it can't contain a newline,
and if you really want to insert a double-quote, you do it with \".
It turns that into the section name "secion.randomstring". The
"section" part is still case insensitive, but the "randomstring"
part is case sensitive.
So you could use this for things like
[email "torvalds@osdl.org"]
name = Linus Torvalds
if you wanted to do the "email->name" conversion as part of the config
file format (I'm not claiming that is sensible, I'm just giving it as an
insane example). That would show up as the association
email.torvalds@osdl.org.name -> Linus Torvalds
which is easy to parse (the "." in the email _looks_ ambiguous, but it
isn't: you know that there will always be a single key-name, so you find
the key name with "strrchr(name, '.')" and things are entirely
unambiguous).
Repo-config is updated to be able to parse the new format, and also
write things out in the new format.

Ok, this was nastier than expected, just because the dependencies between
the different log-printing stuff were absolutely _everywhere_, but here's
a patch that does exactly that.
The patch is not very easy to read, and the "--patch-with-stat" thing is
still broken (it does not call the "show_log()" thing properly for
merges). That's not a new bug. In the new world order it _should_ do
something like
if (rev->logopt)
show_log(rev, rev->logopt, "---\n");
but it doesn't. I haven't looked at the --with-stat logic, so I left it
alone.
That said, this patch removes more lines than it adds, and in particular,
the "cmd_log_wc()" loop is now a very clean:
while ((commit = get_revision(rev)) != NULL) {
log_tree_commit(rev, commit);
free(commit->buffer);
commit->buffer = NULL;
}
so it doesn't get much prettier than this. All the complexity is entirely
hidden in log-tree.c, and any code that needs to flush the log literally
just needs to do the "if (rev->logopt) show_log(...)" incantation.
I had to make the combined_diff() logic take a "struct rev_info" instead
of just a "struct diff_options", but that part is pretty clean.
This does change "git whatchanged" from using "diff-tree" as the commit
descriptor to "commit", and I changed one of the tests to reflect that new
reality. Otherwise everything still passes, and my other tests look fine
too.

The speed of the built-in diff generator is nice; but the function names
shown by `diff -p' are /really/ nice. And I hate having to choose. So,
we hack xdiff to find the function names and print them.
xdiff has grown a flag to say whether to dig up the function names. The
builtin_diff function passes this flag unconditionally. I suppose it
could parse GIT_DIFF_OPTS, but it doesn't at the moment. I've also
reintroduced the `function name' into the test suite, from which it was
removed in commit 3ce8f089.
The function names are parsed by a particularly stupid algorithm at the
moment: it just tries to find a line in the `old' file, from before the
