For what it's worth, Linux's checkpatch.pl script also checks for and
enforces that commit references have this format.
I personally like having the date information, and have attempted to
get checkpatch.pl to stop complaining about the date when it's
included. (see https://patchwork.ozlabs.org/patch/821543/ for the
patch that I've had up, we've been trying to get the maintainer of
checkpatch.pl to notice and pull it in, but not very much success as
of yet).
I'd prefer to keep the format as seen on this list fairly often which
is the something like
show --pretty=%h (\"%s\", %ad) --date=short
or
show --pretty=%h (\"%s\", %cd) --date=short
I like the date since it gives a quick approximation of how long ago
the commit was made, and helps in the rare case of disambiguation.
Personally I also like the quotes since it makes it more obvious where
the subject begins and ends. They aren't strictly necessary but aid
readability to me.
Thanks,
Jake
