inserting a comment into a blank line for nroff (M-;)

[Allan Gottlieb]

Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the bug-gnu-emacs@gnu.org mailing list,
and to the gnu.emacs.bug news group.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

***Have some troff/nroff input say

This is some troff input and
you want a comment between the line.

***You open a blank line to give

This is some troff input and

you want a comment between the line.

then you go to the blank line and type M-; giving

This is some troff input and
\" 
you want a comment between the line.

This is bad since the comment line acts as a blank line which gives a
.sp 1
leaving a blank line.

Instead of \" when a comment is inserted into an empty line
nroff-mode should insert
'\"   (or perhaps .\")

Thanks for emacs.
