I wrote the following shell script function which you can add to your
post-receive-mail script. Any git rev-list --pretty statements there
can have the --pretty removed and have their output redirected to
this, and you get what you want. An existing function changed to use
it follows. Theres probably prettier ways to do this, but hope it
helps. Id send a diff of the script as a whole except that its full of
other likely irrelevent changes.

# show_log_for_sha1s_on_std()
#
# take a list of sha1's on STDIN and print out their logs.
#
# if there are
#
# 0 commits output a notice saying there no changes in this update
#
# 1 commits - show the log only
#
# >1 commits - show log with --name-status output (list of files with
M/D/A type tags
# next to them for Modified Deleted and Added)
#
# This partly exists because we can't use --name-status with rev-list, and
# because we cant use --stdin with git log (even tho the docs might say
# otherwise in older gits). Although since we count SHA1's we can also do some
# special stuff like dealing with the 0/1/N commits differently.
