can this also have something to do with why end-glyphs dont get
hilighted when their extents are hilighted in the case that it's the
end-glyph of the extent at the region-end?

example:

abc[END-GLYPH-of-the-letter-`c']

If I try to highlight that whole line, the end-glyph of `c' doesn't get
highlighed.  Just wondering.
