The 5.22 introduced new deprecation warnings.

The current trunk emits them at every request many times, depending how much plugins are installed.

Examples:

[Thu May 21 17:43:34 2015] Meta.pm: Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/^%META:TOPICINFO{ <-- HERE .*?}%$/ at /me/fw/sites/devmast/foswiki/core/lib/Foswiki/Meta.pm line 3631.

Marking this urgent for 1.2, we can address while workikng to stabilize the unicode core work.

Reopen if any more regex issues encountered.
