Exactly. When the code was moved from expand_path to expand_var, we kept 
the check for the empty string, but expand_var returns the input if it 
cannot expand the variables. It’s simply a bug that doesn’t occur on 
systems (e.g. TL 2013) where both are defined.

Well, I haven't done exhaustive testing, but so far, looks like the beta 
code (2.3) is working as it should.
