e62b393505 Show usage string for 'git show-ref -h'
This only changes the behavior of "git show-ref -h" without any
other options and arguments.

"show-ref -h" currently is short for "show-ref --head", which
shows all the refs/* and HEAD, as opposed to "show-ref" that
shows all the refs/* and not HEAD.

Does anybody use "show-ref -h"?  It was in Linus's original, most
likely only because "it might be handy", not because "the command
should not show the HEAD by default for such and such reasons".
So I think it is okay if "show-ref -h" (but not "show-ref
--head") gives help and exits.

If a current script uses "git show-ref -h" without any other
arguments, it would have to be adapted by changing "-h" to
"--head".

This is a mechanical conversion of all '*.c' files with:

c455c87c5c Rename path_list to string_list
The name path_list was correct for the first usage of that data structure,
but it really is a general-purpose string list.

$ perl -i -pe 's/path-list/string-list/g' $(git grep -l path-list)
$ perl -i -pe 's/path_list/string_list/g' $(git grep -l path_list)
$ git mv path-list.h string-list.h
$ git mv path-list.c string-list.c
$ perl -i -pe 's/has_path/has_string/g' $(git grep -l has_path)
$ perl -i -pe 's/path/string/g' string-list.[ch]
$ git mv Documentation/technical/api-path-list.txt \
	Documentation/technical/api-string-list.txt
$ perl -i -pe 's/strdup_paths/strdup_strings/g' $(git grep -l strdup_paths)

... and then fix all users of string-list to access the member "string"
instead of "path".

Documentation/technical/api-string-list.txt needed some rewrapping, too.

cc44c7655f Mechanical conversion to use prefixcmp()
This mechanically converts strncmp() to use prefixcmp(), but only when
the parameters match specific patterns, so that they can be verified
easily.  Leftover from this will be fixed in a separate step, including
idiotic conversions like

    if (!strncmp("foo", arg, 3))

  =>

    if (!(-prefixcmp(arg, "foo")))

This was done by using this script in px.perl

   #!/usr/bin/perl -i.bak -p
   if (/strncmp\(([^,]+), "([^\\"]*)", (\d+)\)/ && (length($2) == $3)) {
           s|strncmp\(([^,]+), "([^\\"]*)", (\d+)\)|prefixcmp($1, "$2")|;
   }
   if (/strncmp\("([^\\"]*)", ([^,]+), (\d+)\)/ && (length($1) == $3)) {
           s|strncmp\("([^\\"]*)", ([^,]+), (\d+)\)|(-prefixcmp($2, "$1"))|;
   }

and running:

   $ git grep -l strncmp -- '*.c' | xargs perl px.perl

64fe031a7a show-ref: fix --verify --hash=length
An earlier optimization for --verify broke a lot of stuff
because it did not take interaction with other flags into
account.

This also fixes an unrelated argument parsing error; --hash=8
should mean the same as "--hash --abbrev=8".

ed9f7c954c git-fetch: Avoid reading packed refs over and over again
When checking which tags to fetch, the old code used to call
git-show-ref --verify for each remote tag. Since reading even
packed refs is not a cheap operation when there are a lot of
local refs, the code became quite slow.

This fixes it by teaching git-show-ref to filter out existing
refs using a new mode of operation of git-show-ref.

f4204ab9f6 Store peeled refs in packed-refs (take 2).
This fixes the previous implementation which failed to optimize
repositories with tons of lightweight tags.  The updated
packed-refs format begins with "# packed-refs with:" line that
lists the kind of extended data the file records.  Currently,
there is only one such extension defined, "peeled".  This stores
the "peeled tag" on a line that immediately follows a line for a
tag object itself in the format "^<sha-1>".

The header line itself and any extended data are ignored by
older implementation, so packed-refs file generated with this
version can still be used by older git.  packed-refs made by
older git can of course be used with this version.

358ddb62cf Add "git show-ref" builtin command
It's kind of like "git peek-remote", but works only locally (and thus
avoids the whole overhead of git_connect()) and has some extra
verification features.

For example, it allows you to filter the results, and to choose whether
you want the tag dereferencing or not. You can also use it to just test
whether a particular ref exists.

For example:

	git show-ref master

will show all references called "master", whether tags or heads or
anything else, and regardless of how deep in the reference naming
hierarchy they are (so it would show "refs/heads/master" but also
"refs/remote/other-repo/master").

When using the "--verify" flag, the command requires an exact ref path:

	git show-ref --verify refs/heads/master

will only match the exact branch called "master".

If nothing matches, show-ref will return an error code of 1, and in the
case of verification, it will show an error message.

For scripting, you can ask it to be quiet with the "--quiet" flag, which
allows you to do things like

	git-show-ref --quiet --verify -- "refs/heads/$headname" ||
		echo "$headname is not a valid branch"

to check whether a particular branch exists or not (notice how we don't
actually want to show any results, and we want to use the full refname for
it in order to not trigger the problem with ambiguous partial matches).

To show only tags, or only proper branch heads, use "--tags" and/or
"--heads" respectively (using both means that it shows tags _and_ heads,
but not other random references under the refs/ subdirectory).

To do automatic tag object dereferencing, use the "-d" or "--dereference"
flag, so you can do

	git show-ref --tags --dereference

to get a listing of all tags together with what they dereference.
