Case sensitivity lost when using [A-Z] or [a-z] style wildcarding in tcsh.

eg: [A-Z]*  and [a-z]* both produce the same results (the equivalent of
[A-Za-z]*)

Problem noticed on an upgrade from RH6.0 to RH6.1. Replacing executable of
/bin/tcsh with RH6.0 versions does not help.

/bin/bash does not seem to be effected.

System:

   Intel Pentium III.

Ta!
