Just today, I got a bug report from one of our developers. The git update hook we had in place before the conversion to 1.5 had this: chmod -R ug+w $GIT_DIR to avoid problems when people used 'git ssh://...", due to different umasks (yeah, a hack). So, moving to 1.5, I updated our script (and, had been updating it for quite some time, so many revisions, maybe 20 or so), and well, now when people use ssh, they leave behind directories others can't read (as git now allows push through "git://", we'll be weaning people off of ssh soon). So, I wanted to say "give me the first version of this, so I can cut-n-paste the chmod command, since I can't remember if it was chmod, or chown, or some combination ...", and thus the desire to to: % git log -p HEAD~"All the way back" update or something similar.
