*That* i would call a bug.  I think that of

    Str.string_match (Str.regexp "a") "xa" 0;;
    Str.string_match (Str.regexp "a") "ax" 0;;

either both should evaluate to true, or neither should.  Both evaluating to
true would match the typical perl/grep/etc. notion of searching anywhere
inside a string to for a matching substring, whereas neither doing so would
correspond to the mathematical notion of containment in the language of a
regular expression.
