git: updated to 2.37.2

Git 2.37.2 Release Notes
========================

This primarily is to backport various fixes accumulated on the 'master'
front since 2.37.1.

Fixes since v2.37.1
-------------------

 * "git shortlog -n" relied on the underlying qsort() to be stable,
   which shouldn't have.  Fixed.

 * Variable quoting fix in the vimdiff driver of "git mergetool".

 * An earlier attempt to plug leaks placed a clean-up label to jump to
   at a bogus place, which as been corrected.

 * Fixes a long-standing corner case bug around directory renames in
   the merge-ort strategy.

 * Recent update to vimdiff layout code has been made more robust
   against different end-user vim settings.

 * In a non-bare repository, the behavior of Git when the
   core.worktree configuration variable points at a directory that has
   a repository as its subdirectory, regressed in Git 2.27 days.

 * References to commands-to-be-typed-literally in "git rebase"
   documentation mark-up have been corrected.

 * Give _() markings to fatal/warning/usage: labels that are shown in
   front of these messages.

 * "git mktree --missing" lazily fetched objects that are missing from
   the local object store, which was totally unnecessary for the purpose
   of creating the tree object(s) from its input.

 * Fixes for tests when the source directory has unusual characters in
   its path, e.g. whitespaces, double-quotes, etc.

 * Adjust technical/bitmap-format to be formatted by AsciiDoc, and
   add some missing information to the documentation.

 * Certain diff options are currently ignored when combined-diff is
   shown; mark them as incompatible with the feature.

 * "git clone" from a repository with some ref whose HEAD is unborn
   did not set the HEAD in the resulting repository correctly, which
   has been corrected.

 * mkstemp() emulation on Windows has been improved.

 * Add missing documentation for "include" and "includeIf" features in
   "git config" file format, which incidentally teaches the command
   line completion to include them in its offerings.

 * Avoid "white/black-list" in documentation and code comments.

 * Workaround for a compiler warning against use of die() in
   osx-keychain (in contrib/).

 * Workaround for a false positive compiler warning.

 * The resolve-undo information in the index was not protected against
   GC, which has been corrected.

 * A corner case bug where lazily fetching objects from a promisor
   remote resulted in infinite recursion has been corrected.

 * "git p4" working on UTF-16 files on Windows did not implement
   CRLF-to-LF conversion correctly, which has been corrected.

 * "git p4" did not handle non-ASCII client name well, which has been
   corrected.

 * "rerere-train" script (in contrib/) used to honor commit.gpgSign
   while recreating the throw-away merges.

 * "git checkout" miscounted the paths it updated, which has been
   corrected.

 * Fix for a bug that makes write-tree to fail to write out a
   non-existent index as a tree, introduced in 2.37.

 * There was a bug in the codepath to upgrade generation information
   in commit-graph from v1 to v2 format, which has been corrected.

Also contains minor documentation updates and code clean-ups.
