But you can't just write for an XFree86 world, so you can't assume all
non-suitable font directories are removed from the font path variable.
Besides, the user can set it later to what they prefer.

Yes, I'm not suggesting xdpyinfo or X -probeonly.  Just xset to query
the font path.  But your test is inadequate and both Stewart and I have
pointed that out repeatedly, and I've provided some simple awk to do a
better test.

Your statement `100 is always good, except if there aren't any 100
fonts' is false.  100 may be a poor substitute for 75 and 75 should be
used in preference.  That's why, for example, it appears sooner in the
font path.  And that's why the awk looked along the font path to see
what was specified first.

So either hardcode 100 or put in a better test than `grep'.

My point was that it seems like feeping creaturism for groffview to do
this since it is already available with man, especially if your man has
-w available, which mine doesn't  :-)  It's not part of the Single UNIX
Specification, Version 2.

So it'll either not work because man doesn't have -w, or it probably
isn't worth having since cat will do the same job.

    cat `man -w true`
