Hello Richard,

For some reason, the -p flag for ed requires a non-empty arguement. Is
this really necessary?
Of course it isn't really necessary, but it is documented[1][2][3] this
way and so I have maintained it this way.

I edited carg_parser.c, commented out lines
194-196 and it still works perfectly.
You did what? If all you want is to make the argument to -p optional,
you should have changed line 148 of main.c to
{ 'p', "prompt", ap_maybe },
I only did this because without
the -p flag, ed does not output correctly when using a netcat bind
shell. I believe this has something to do with how ed handles output.
I don't know exactly why though.
What do you mean by "ed does not output correctly"?
Did you try to toggle the prompt with the 'P' command?
Regards,
Antonio.
