Nitpicking: display_string doesn't display anything, it just prepares
glyph structures used by other code to actually display the mode line
on the glass.

I don't want to argue with your reading of the code.  I'm saying that
the natural way of removing extra spaces is to post-process the glyphs
produced by display_string directly; anything else is IMO inelegant
and unnatural.
