Ok, here's something to chew on:

chip at chip1:~> echo abc | grep A
chip at chip1:~> echo abc | grep a
chip at chip1:~> echo abc | grep "[A-Z]"
chip at chip1:~> export LANG=C
chip at chip1:~> echo abc | grep "[A-Z]"

The distribution is SuSE enterprise linux.  It seems that the LANG stuff
only affects an expression in set of mini-experiments.  

Another thing that is odd is that there are many programs in /usr/bin with
symlinks to their counterpart in /bin.  However, /usr/bin isn't a symlink
to /bin.  I guess SuSE is "non-standard", but I thought it was a Red Hat
