- update to 2.47.0:
* https://raw.githubusercontent.com/git/git/master/Documentation/RelNotes/2.47.0.txt
* Many Porcelain commands that internally use the merge machinery
were taught to consistently honor the diff.algorithm
configuration.
* A few descriptions in "git show-ref -h" have been clarified.
* A 'P' command to "git add -p" that passes the patch hunk to the
pager has been added.
* "git grep -W" omits blank lines that follow the found function at
the end of the file, just like it omits blank lines before the next
function.
* The value of http.proxy can have "path" at the end for a socks
proxy that listens to a unix-domain socket, but we started to
discard it when we taught proxy auth code path to use the
credential helpers, which has been corrected.
* The code paths to compact multiple reftable files have been updated
to correctly deal with multiple compaction triggering at the same
time.
* Support to specify ref backend for submodules has been enhanced.
* "git svn" has been taught about svn:global-ignores property
recent versions of Subversion has.
* The default object hash and ref backend format used to be settable
only with explicit command line option to "git init" and
environment variables, but now they can be configured in the user's
global and system wide configuration.
* "git send-email" learned "--translate-aliases" option that reads
addresses from the standard input and emits the result of applying
aliases on them to the standard output.
* 'git for-each-ref' learned a new "--format" atom to find the branch
that the history leading to a given commit "%(is-base:)" is
