user. I previously suggested to Nuno that newline options be made
available to PHP users (don't know the status). With your fix, the
option would already be there. Without it, users are stuck with
whichever newline option was made the default. Which newline would be
wanted has more to do with the user's data than anything else, and is
especially useful for processing multiline data with ^ and $ matching
where they should.
About the issue of it needing to be at the start of the pattern, could
it possibly also be supported after a leading (?#comment) ?
