I have been pondering an incompatible change in ecl so as to change the
case of translated pathnames using :CASE :COMMON. That means uppercased
pathnames get translated to the local convention of the filesystem,
lowercased pathnames get translated to the opposite and mixed case
pathnames are left untouched.

That would break code in ECL and code which assumes that logical
pathnames with lower case components are to be preserved as such. 

Just a thought. I appreciate feedback.
