I don't quite understand.  As in, you do C-s to search for "^a[ ]
+regexp", it doesn't match, so then it works as if you did C-M-s (or M-
r in isearch-mode) so it interprets the string as a regexp?  Why
wouldn't you just use C-M-s (or M-r from isearch-mode)?

I guess what I was going for with flex-isearch is to find similar
strings if I mistyped the search string, or make it a bit more
forgiving if I didn't know the exact string.  If I'm searching for a
regexp, then I know I'm searching for a regexp, and in my mind it's a
different operation than a simple string search.
