But I do want to do one of those, to solve bug 22634: I want
   <glob pattern="core"/> to be case-sensitive="true".

How about a different hack:
we generate in globs2 two lines, in case of case-sensitive:
50:text/x-c++src:*.C
50:text/x-c++src:*.C:cs
Old parsers will create an entry for "*.C:cs", which will probably never match 
any real file, so no big deal, while new parsers will take the second line as 
an indication that the *.C glob (parsed one line above) should be understood 
to be case sensitive.
