I'm still a bit shaky on exactly what to call these files, but I've
gathered the roff, troff, groff, and nroff all pretty much refer to the
same format (listed as application/x-troff in Trac). These include
manpage source, of which one file exists in the Trac source tree.
Its extension is not matched by the current trac/mimeview/api.py
(either of the two identical lines, hrmm), but extensions are specified
in the Pygments lexer for it (since
http://trac.pocoo.org/changeset/2424). Do you think it is feasible for
the renderer's lexers' extensions (which are admittedly in fnmatch
style) from Pygments to be overlaid to KNOWN_MIME_TYPES (or otherwise
made available to get_mimetype) at runtime?
I've patched get_mimetype to do this[1], but I'm slightly wary of
putting code to call Pygments in the core, even wrapped with a
try/catch block[2]. Opinions?

[1]: the fun part is...
from pygments import get_lexer_for_filename
mimetype = get_lexer_for_filename(filename).mimetypes[0]
[2]: if it finds the mimetype is not already in the mapping, it
probably needs to make sure something will be findable to render it
too, making this kind of messy for new mimetypes. Luckily this
particular one already exists.
