Arc bugreport: URL matching error with “.../);”

See comment below.

I understand the mods see virtually all new posts regardless of vote count. If this has no replies within 18-24h I'll look for other contact mechanisms.

This is an experiment in reporting HN-specific Arc bugs via HN itself. I once reported this via the Arc forum, but it went unnoticed (which was kind of easy since the testcase I posted didn't work on the Arc version running there!).

If the mods would strongly prefer I email this type of thing in future, I can accept that.

Also, an aside: the "..." in the post title was initially removed (".../);" --> "/);"), I had to edit it back in. The "..." is definitely present on the submission page in my history. I'm very curious why this happened (I don't suspect it's a bug).
