The 4th value is unimportant: it's the font's glyph index for that
character's glyph. The 5th element is the problem: it's what we use
for the glyph. 29 is way too large, about 2.5 times too large.
So the question now becomes how come we get such a large value. Looks
like we somehow use the space-width value instead of the character
glyph's width, not sure why. I guess stepping through the code I've
shown from xdisp.c is still necessary to understand this.
