I was playing around with the new 'theme' setting in ./.tm_properties.

Given the file: ./webapp/WEB-INF/web.xml

this works:
[ "text.xml" ]
theme = 71D40D9D-AE48-11D9-920A-000D93589AF6

this does not:
[ "*.xml" ]
theme = 71D40D9D-AE48-11D9-920A-000D93589AF6

this works:

[ "webapp/**" ]
theme = 71D40D9D-AE48-11D9-920A-000D93589AF6

this does not:

[ "webapp/WEB-INF/**"]
theme = 71D40D9D-AE48-11D9-920A-000D93589AF6

It was my understanding that all of these selectors should apply the setting to this file?  What am missing?
