[Feature Request] Highlight current selection region as iedit did.

[zw963]

e.g. i only want to highlight the overlay part of the symbol symbol-overlay-put, so, i will set mark and highlight that region first, then run symbol-overlay-put, but, it still highlight entire symbol-overlay-put part.

Following is the same effect when use with iedit package, it works as expected.

thank you.
