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.
