Hi,
thanks for your answer. Let me pose the question again:
string-match asks, if a regexp is contained by string.
(equal "" "foo") reads a quite different question for me, as (string-match "^$" "foo") does.
Why should questioned string respond here it contains an empty string at position 0?
Makes no sense for me.
Andreas
