Please see attached.

2.patch is a part which changes how cmdedit_set_out_char works.
It renames two badly names functions, uses "clear to end of screen"
to eliminate annoying problems with clearing wide chars, and such.
Run tested. I will apply it to git. Please review.

I renamed the function to put_cur_*glyph*_and_inc_cursor, not
put_cur_*char*_and_inc_cursor, because for combining chars,
it will print _more than one_ (unicode) char.

3.patch is the remainder of your patch. Not reviewed yet.
