Subject: [PATCH] Do not mess up page content with leading slashes.

If a page title started with a slash, the algorithm to deal with leading
capitals would produce a faulty regexp by accessing $escapedTitle[0] and
substr($escapedTitle, 1), which would only capture the slash that escapes
the slash.

Also fix small bug in template detection (make expression non-greedy).
