From jilles: POSIX requires that a script set `OPTIND=1` before using different sets of parameters with `getopts`, or the results will be unspecified. The specific problem observed here is that we would execute `man -f` or `man -k` without cleaning up state from man_parse_args()' `getopts` loop. FreeBSD's /bin/sh seems to reset OPTIND to 1 after we hit the second getopts loop, rendering the following shift harmless; other /bin/sh implementations will leave it at what we came into the loop at (e.g., bash as /bin/sh), shifting off any keywords that we had.
