Change various cmd_* functions to use "return" instead of exit() to indicate an exit code. On Solaris with SunCC the compiler legitimately complains about these, since we'll e.g. skip the cleanup (e.g. closing fd's, erroring if we can't) in git.c's run_builtin() when we exit() directly like this.

A trivial issue noticed in my pre-v2.32.0 testing that I wanted to leave until after the release.
