Relative URLs beginning with // should not be converted

This was already fixed in #2079001: Network path reference urls (//) should not be prefixed → .

There's a check:
&& substr($txt, $pos, 2) != '//' to ensure the string doesn't start with "//".

The attached patch adds a simple case to the module's functional test to verify this.

tnx
