Update Information:

Upstream update including security & bug fixes as well as feature enhancements.
From the upstream [release notes](  https://github.com/git/git/raw/v2.38.1/Documen
tation/RelNotes/2.30.6.txt): CVE-2022-39253 -------------- When relying on
the `--local` clone optimization, Git dereferences symbolic links in the source
repository before creating hardlinks (or copies) of the dereferenced link in the
destination repository. This can lead to surprising behavior where arbitrary
files are present in a repository's `$GIT_DIR` when cloning from a malicious
repository. Git will no longer dereference symbolic links via the `--local`
clone mechanism, and will instead refuse to clone repositories that have
symbolic links present in the `$GIT_DIR/objects` directory. Additionally, the
value of `protocol.file.allow` is changed to be "user" by default.
CVE-2022-39260 -------------- An overly-long command string given to `git
shell` can result in overflow in `split_cmdline()`, leading to arbitrary heap
writes and remote code execution when `git shell` is exposed and the directory
`$HOME/git-shell-commands` exists. `git shell` is taught to refuse interactive
commands that are longer than 4MiB in size. `split_cmdline()` is hardened to
reject inputs larger than 2GiB. Credits ------- Credit for finding
CVE-2022-39253 goes to Cory Snider of Mirantis. The fix was authored by Taylor
Blau, with help from Johannes Schindelin. Credit for finding CVE-2022-39260
goes to Kevin Backhouse of GitHub. The fix was authored by Kevin Backhouse, Jeff
King, and Taylor Blau.
