This fixes an infinite recursion bug caused by visiting a bad subpage of the help handler repeatedly, which caused the wrapper for the templater's escape filter to get installed twice and resulted in infinite recursion.

'''expand expressions into changelog and summaries
|
|
|
|
This extension allows the use of a special syntax in summaries, which
|
|
will be automatically expanded into links or any other arbitrary
|
|
expression, much like InterWiki does.
|
|
|
|
A few example patterns (link to bug tracking, etc.) that may be used
|
|
in your hgrc::
|
|
|
|
[interhg]
|
|
issues = s!issue(\\d+)!<a href="http://bts/issue\\1">issue\\1</a>!
|
|
bugzilla = s!((?:bug|b=|(?=#?\\d{4,}))(?:\\s*#?)(\\d+))!<a..=\\2">\\1</a>!i
|
|
boldify = s!(^|\\s)#(\\d+)\\b! <b>#\\2</b>!
