I have a function perldoc that looks like this:

  (defun perldoc (man-args)
    (interactive "sPerldoc: ")
    (require 'man)
    (let ((manual-program "perldoc"))
      (man man-args)))

And perldoc has a -F switch which extracts documentation from a

It doesn't work to say

M-x perldoc RET -F SPC bla RET

where bla is a relative filename, because of some magic in
Man-getpage-in-background.  I've tried the following fix:

        ;; Prevent any attempt to use display terminal fanciness.

It seems to work.  What do people think?
