Oh, that must be a bug. Can you file it here please with details of
exactly how to reproduce it:

Yes, though perhaps not very clearly:
http://haskell.org/cabal/release/latest/doc/users-guide/authors.html#pkg-descr

        The syntax of the value depends on the field. Field types
        include:
        
        token , filename , directory 
                
                Either a sequence of one or more non-space non-comma
                characters, or a quoted string in Haskell 98 lexical
                syntax. Unless otherwise stated, relative filenames and
                directories are interpreted from the package root
                directory.
                
Suggestions for improvement welcome. Even better would be patches. The
user guide is in the Cabal repo in doc/Cabal.xml in docbook format.
