Subject: bug#31584: 27.0.50; Document again what match re-search-backward finds
Date: Thu, 24 May 2018 23:31:03 +0200 [thread overview]
Message-ID: <87in7cg2qw.fsf@web.de> (raw)
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.
