Huh? I'm really confused. Two people think the documentation
is correct for the behaviour.
I do not -- Saying
string x is matched by regexp r
means to me the same as
x is a member of the regular set of strings r denotes
and with that interpretation there is no possible doubt that
the documentation is wrong and should say
matches a prefix of the argument string
in order to describe the behaviour.
