Currently there are some inconsistencies in the JSPWiki plugins.
In the first table below this is illustrated, in the second table the proposed new situation (red are the changes).
Switching from Regular Expressions to Glob Expressions is an incompatible change off course.

Current situation#

Plugin	AbstractReferralPlugin Subclass	Use Glob expressions	Use Regular expressions
ReferringPagesPlugin	x	x
UndefinedPagesPlugin	x	x
UnusedPagesPlugin	x	x
RecentChangesPlugin
ReferredPagesPlugin			x
IndexPlugin	x		x
PluginIndexPlugin	x

New situation#

Plugin	AbstractReferralPlugin Subclass	Use Glob expressions	Use Regular expressions
ReferringPagesPlugin	x	x
UndefinedPagesPlugin	x	x
UnusedPagesPlugin	x	x
RecentChangesPlugin	x	x
ReferredPagesPlugin	x	x
IndexPlugin	x	x
PluginIndexPlugin	x

Looks good to me. Glob expressions are user-friendly, unlike perl regexps. BTW, we might want to rename "AbstractReferralPlugin" to "AbstractFilteredPlugin".
