Ship it! The glob to regex conversion was not initially supposed to accept user input as its argument that's why it lacked the checks for valid glob expressions. But now it looks like these checks are necessary for this case. - Seth On June 20, 2011, 8:21 p.m., Squire Linden wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
