The backward compat breakage is for people who already have all kinds of
arbitrary characters in filenames *and* use `NAME/` rules. See the doc
change in this commit for details and mitigation. See this link for
background:

Thanks to Dan Carpenter for the audit.
you might wonder why these are different from all the other variables in
the rc file... it's just that I never thought people would want to
change these!
- allow a mob username to be defined; all unauthenticated access will
look to gitolite like this user (if you setup apache also properly)
- update doc with more details (some repeat stuff from `man
git-http-backend` but it's probably worth having everything in one
place
