Log Message:
sh(1): improve getopts docs for optstring leading :

getopts has different behaviour if the leading character
of optstring is `:', so describe in more detail:
- no errors are printed (already there)
- unknown options set var to `?' and OPTARG to the unknown option
- missing arguments set var to `:' and OPTARG to the option name

Slight rewording of other paragraphs for more clarity.
