The standard format for referencing other commits within some projects
(such as git.git) is the summary format. This is described in
Documentation/SubmittingPatches as
If you want to reference a previous commit in the history of a stable
branch, use the format "abbreviated sha1 (subject, date)",
with the subject enclosed in a pair of double-quotes, like this:
....
Commit f86a374 ("pack-bitmap.c: fix a memleak", 2015-03-30)
noticed that ...
....
Since this format is so commonly used, standardize it as a pretty
format.
This format is implemented as a separate flow that skips most of
pretty_print_commit() and instead calls format_commit_summary(). The
reason why this is done is because the other pretty formats expect
output to be generated in a specific order. Specifically, the header,
including the date, is always printed before the commit message,
including the subject. Reversing the order would be possible but would
involve butchering pretty_print_commit() so it is implemented as a
separate flow.
