Yup, I had the same reaction.  Instead of restricting the namespace
of branches even on systems that do not have this problem, use a ref
backend that is not limited by the underlying filesystem.  A much
better solution.

In addition to the LMDB backend, it might not be a bad idea to add
another filesystem-based backend that encodes the refnames safely on
case insensitive or case destroying filesystem.  That way, those who
do not want an extra dependency but do want case sensitive refnames
would have an option, and having two non-default backends with quite
different semantics may be a good way to ensure that the API for
refs backend is kept sane.
