Hi,
could someone please shed a light on the purpose of overlays? I`m
wondering under what circumstances they are used, or need to be used.
Are they a feature that has been obsoleted by font-lock, or are they
still needed?
The background is that I`ve made an extension to hi-lock.el, and hi-lock
features alternatively using overlays or font-lock. My extension does
not support overlays, and I`m wondering if support for overlays needs to
be added or not.
