$ rpm -q groff
From the groff(7) man page:
| Single-Character Escapes
| \. An uninterpreted dot (period), even at start of line.
(See also the first bullet point in "CONTROL CHARACTERS".)
However, it doesn't seem that the this escape works as documented, assuming I understand how to use it correctly. Reproducer:
$ cat t.man
$ groff -Tascii -wmac ./t.man | head -n 1
./t.man:2: warning: macro `bar' not defined
I think the output should have been "foo .bar quux" and no warning.
According to upstream response, this is an expected behavior. And it should be fixed in manual page.
It seems that it's still unfixed in the man page as of groff 1.21-8.fc17. I'm wondering what _is_ the way to get uninterpreted dots at start of line if \. is not it?
Sorry for that. I still do not know what exactly is the correct behavior and what should be stated in the manpage. I will need to search some old roff documentation.
You can take a look at following threads:
One possible way of printing dot at the beginning of the line is this:
groff -Tascii -wmac <<< '\[char46]foo' | head -1
But I think there is also another escape sequence.
