(note_mouse_highlight) <help-echo>: When looking for 

help-echo for a string which doesn't have help-echo itself, use
get-char-property to obtain the help-echo from the string's buffer
(note_mouse_highlight) <mouse-face>: When on a string that doesn't
have mouse-face, look for mouse-face ``under'' the string for
mouse-face from an overlay.
(fast_find_position): Add parameter STOP.  In the final row,
stop before glyphs having STOP as object.  Don't consider
glyphs that are not from a buffer.

* xterm.c (note_mouse_highlight) <help-echo>: When looking for
help-echo for a string which doesn't have help-echo itself, use
get-char-property to obtain the help-echo from the string's buffer
(note_mouse_highlight) <mouse-face>: When on a string that doesn't
have mouse-face, look ``under'' the string for mouse-face from an
overlay.
(fast_find_position): Add parameter STOP. In the final row, stop
before glyphs having STOP as object. Don't consider glyphs that
are not from a buffer.
* buffer.c (syms_of_buffer) <default-directory>: Doc fix.
