Problem: filetype: nroff detection can be improved
Solution: improve nroff detection (Eisuke Kawashima)
- explicitly check roff comments and macros typically found in manpages
- do not try to detect alphabetically-sectioned files, except for n, as
nroff
- l: > 'l' happens to be a section for historical reasons
<https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=391977>
- n: e.g. /usr/share/man/mann/Tcl.n.gz
- o: unsure (perhaps fedora-specific)
- p: unsure (perhaps fedora-specific)
closes: #17160
