Hello,
a user asked in emacs-help why
(re-search-backward "a*")
at the end of a line consisting only "a"s didn't move point. With
today's documentation, that question can't be answered.
Some time ago, we had this sentence in the docstring:
The match found is the one starting last in the buffer
and yet ending before the origin of the search.
but it has been removed. I think we need to say something like that,
otherwise the semantics of backward re search is unclear.
TIA,
Michael.
