Re: undo custom delete

["Shug Boabby" <Shug.Boabby@gmail.com>]

and also, i'd have to ensure that the character deleted wasn't
whitespace and that it was beside the last character deleted... or undo
would undo not just the last word, but the last N deletes until it
encounters whitespace!

a pre command hook sounds like the way to do it. if anyone wants a
little project to work on for a few hours, please be my guest! i'll try
when i get time.

could somebody please describe the buffer-undo-list in more detail to
me... specifically, how do i tell which action was performed, where the
action was performed, and if it was a deletion, what was deleted.
