Supplant the "while case ... break ;; esac" idiom
A lot of shell scripts contained stuff starting with while case "$#" in 0) break ;; esac and similar. I consider breaking out of the condition instead of the body od the loop ugly, and the implied "true" value of the non-matching case is not really obvious to humans at first glance. It happens not to be obvious to some BSD shells, either, but that's because they are not POSIX-compliant. In most cases, this has been replaced by a straight condition using "test". "case" has the advantage of being faster than "test" on vintage shells where "test" is not a builtin. Since none of them is likely to run the git scripts, anyway, the added readability should be worth the change. A few loops have had their termination condition expressed differently.
