Hi there,
the 'l' command in base ed currently does not mark the end of line with a '$'.
This is documented in the man page (POSIX wants each '$' escaped, and a final
'$' at EOL). Interestingly, the code to mark EOL is already there, just hidden
by the BACKWARDS flag ed is compiled with. Here is a small diff that removes
the BACKWARDS guard around the EOL marker. The resulting behavior is equal to
GNU ed, base vi and vim (:set list).
Removing the BACKWARDS flag would fix it as well, but i don't see the need for
that. There is some code that could be deleted in that case, though (mostly
different error messages).
Any comments?
Kind regards
Nils
