]] You may wonder why I am using GNU ed on OSX instead of the BSD version and
the answer is simply that GNU ed supports the '#' comment command syntax and
BSD ed does not.
The comment command was added just prior to the release of the GNU port of
ed(1), so it should be in BSD ed(1) as well. If not that was a mistake that
should be corrected. If POSIX compliance is a concern, be aware that the
comment command is not in the POSIX spec. The GNU ed and BSD ed behavior
should otherwise be identical.

The GNU ed(1) flag -G (—traditional) enforces POSIX syntax - the same as if
the environment variable POSIXLY_CORRECT were set. The intent is to allow GNU
ed(1) to run POSIXLY_CORRECT scripts. The POSIX cases are mostly syntax
