Hi!
The backslash-period escape sequence in groff doesn't work as described in
documentation.
Manual page:
\. An uninterpreted dot (period), even at start of line.
Minimal reproducer:
$ groff -wmac -Tascii <<< '\.foo'
<standard input>:1: warning: macro `foo' not defined
Original report in Fedora:
https://bugzilla.redhat.com/show_bug.cgi?id=682857
I'm attaching a proposed patch. But I suppose there is a better way of fixing
it. This looks a little bit like a workaround. It is just the easiest way with
the least modifications of the code.
