One think I'd suggest is using OVERWRITE instead of OVERSTRIKE, since
that's what the corresponding zle widget is called; there's no use of
"overstrike" in the documentation at present, and it vaguely suggests to me
a visual effect such as two characters on top of one another or a line
through.  You might also want to refer to the overwrite-mode widget.

Apart from that, this looks useful; the only thing that might make a
difference is if there was some other information that could be combined
with this and the result presented in a more compact way, such as a set of
flags in a single variable.  However, I can't think of anything that would
fit that bill, and the code is minimal anyway.
