The "git-resurrect.sh" script can be used to find traces of a branch tip
in the reflog and resurrect that branch. Despite a couple of global
cleanups, the script hasn't seen any activity since it was introduced in
e1ff064e1bf (contrib git-resurrect: find traces of a branch name and
resurrect it, 2009-02-04).
Furthermore, the tool does not work with the "reftable" backend at all
as it directly reads ".git/logs/HEAD". As reflogs are stored as part of
the individual tables though that file wouldn't exist in a "reftable"-
enabled repository.
Last but not least, the tool doesn't even work unless it is explicitly
invoked via `git resurrect` as it sources "git-sh-setup". As none of our
build systems know to install this script, users thus have to go out of
their way to really make it work, which is highly unlikely.
Another source that indicates that this tool can be removed is a
question for how to restore deleted branches on StackOverflow [1]. The
top-voted answer uses git-reflog(1) directly and has received more than
3000 votes to date. While "git-resurrect.sh" is also mentioned, it only
got 16 upvotes, and comments mention the above caveat that users have to
do some manual setup to make it work.
It's thus rather clear that the tool doesn't have a lot or even any
users. Remove it.

Since Git now supports hashes other than SHA-1, the hash length isn't
guaranteed to be 40 characters. Replace $_x40 with a hash-agnostic OID
pattern.

In the git-resurrect script, there are a few lines that are mistakenly
indented with spaces. Replace these lines with tabs.

Code cleanup.
* jc/bs-t-is-not-a-tab-for-sed:
contrib/git-resurrect.sh: do not write \t for HT in sed scripts
|

Just like we did in 0d1d6e50 ("t/t7003: replace \t with literal tab
in sed expression", 2010-08-12), avoid writing "\t" for HT in sed
scripts, which is not portable.

If the variable $OPTIONS_STUCKLONG is not empty, then rev-parse
option parsing is done in --stuck-long mode.

Like most git commands, request-pull supports a -- delimiter to allow
callers to pass arguments that would otherwise be treated as an option
afterwards. The internal OPTIONS_KEEPDASHDASH variable is passed
empty to git-sh-setup to indicate that request-pull itself does not
care about the position of the -- delimiter. But if the user has
that variable in her environment, request-pull will see the “--” and
fail.
Empty it explicitly to guard against this. While at it, make the
corresponding fix to git-resurrect, too (all other scripts in git.git
already protect themselves).

Add a tool 'git-resurrect.sh <branch>' that tries to find traces of
the <branch> in the HEAD reflog and, optionally, all merge commits in
the repository. It can then resurrect the branch, pointing it at the
most recent of all candidate commits found.
