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. > OK, I've now done some more testing -- I removed my call to > display_string, and no mode line is displayed at all, which kinda > supports my reading of the code? 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.
