It looks like this issue is due to pygments.lexers.get_all_lexers() having
multiple mime types associated with this extension.
('C', ('c',), ('*.c', '*.h', '*.idc', '*.x[bp]m'), ('text/x-chdr',
'text/x-csrc', 'image/x-xbitmap', 'image/x-xpixmap'))
So, in mimeview.py, Mimeview.mime_map(), there are multiple assignments to
self._mime_map[keyword] = mimetype
It will assign to the four items in the above list in turn. However,
self._mime_map will simply end up holding the last value.
I wonder if we should just use the first one we encounter, and ignore
subsequent attempts to override the value.
I am using Ubuntu 22. (pygments 2.11 or 2.12)
