True.  Other examples are Rational Rose .mdl files, Power Designer .pdm
files, which are ASCII files but effectively non mergeable.  CVS sort of
handles this type of file through the cvswrappers file using the -m 'COPY'

Oh, I don't want to eliminate keyword expansion completely - I only want to
eliminate it for binary files.  I too prefer to see keywords expanded with
their values ("kv") in non-binary files for general use.  If the occasional
conflict from keyword expansion during merging is acceptable (e.g. no
keyword expansion override is supplied in update or checkout), then that's
fine - I'm not recommending a change that would affect that default
