That sounds worse than it is once you realize that those 47 pdf are in
something like 10 different languages, so people are going to use only a
subset of those anyway.

What's the tree size for "make doc"?  How does it deal with older
versions of Ghostscript?

At any rate: is there any reason for us to actually use glyphshow at all
considering its apparent drawbacks?  Or is it intended more for things
that should be treated like glyphs but are produced on-the-fly?  Like
beams and stems and such: we do those using graphical commands right now
but that does not allow for things like hinting.
