I *think* you have hit it on the head, and I'm hoping it's just a PHP bug when
the moved to the JIT implementation for split().
From:
http://perldoc.perl.org/perlre.html
s
Treat string as single line. That is, change "." to match any character
whatsoever, even a newline, which normally it would not match.
Used together, as /ms, they let the "." match any character whatsoever, while
still allowing "^" and "$" to match, respectively, just after and just before
newlines within the string.
And you're right, /u is for unicode.
