m//gc does not reset search position on failure

The m//g match iteration construct has always reset its target string's search position (which is visible through the pos operator) when a match fails; as a result, the next m//g match after a failure starts again at the beginning of the string. With Perl 5.004, this reset may be disabled by adding the ``c'' (for ``continue'') modifier, i.e. m//gc. This feature, in conjunction with the \G zero-width assertion, makes it possible to chain matches together. See the perlop manpage and the perlre manpage.
