Taint functions and $1

[Christian Robottom Reis]

I'm not a Perl wizard, and therefore running into 

    https://bugzilla.mozilla.org/show_bug.cgi?id=297928

was a surprise for me today. Moral of the story: don't rely on the
value of $1 if the match for something failed; failed matches don't
reset $1. Code that does

    $foo =~ /(\d+)/;
    $bar = $1;

is buggy for the same reason.

Take care,
