Backward compatibility

[grylem]

Hi
macOS version o the ed must be posix compliant

printf %s\n H '# test' q | ed
?
script, line 2: unknown command

your versions works like gnu ed

printf %s\n H '# test' q | ed
no any messages

if add -G still works like gnu ed, is that how it should be? If yes, how to use your version of ed as posix compatible?

Support for comments is not traditional in ed, so:

printf "%\n" H '# test' | ed -G

should really print an error. I'll correct that. Thank you!

By the way, macOS ed actually quits, which is incorrect. When ed reads commands from a pipe, the traditional behavior is to reports errors, but not exit. A lot of scripts depend on this behavior. macOS ed is actually an early version of my code, from before this was corrected. Unfortunately, there's no way to fix it now :(

Thanks for explanaion.

P.S.
in manpage and texinfo file info about options as -eIRx are missed. Please fix it.

Yeah, the documentation needs a lot of work. In the mean time, the file doc/SUSv4.md does a little better job of covering extensions.

HEAD of branch without-gnulib should now be in sync with main branch.
