Hmm, I think this should be a dirstate member - only the filesystem
has case folding behaviour, and the dirstate reflects the working
directory, ie the filesystem. The repository is in theory always case
sensitive as filenames get mangled to ensure this.

There may be places where the repo needs to know about case issues -
my paych for issue 1083 is a case in point - but that's only in order
to know that it needs to work around a case insensitive filesystem in
order to enforce case sensitive semantics.

Does that make sense? (I ask because I want to check that my
understanding of the concepts involved is correct...)
Paul.
