On a RH5 box, I don't get anything returned from  echo abc | grep "[A-Z]"
and LANG is en_US.UTF-8.  I'd check to see if it is always reproducible on
SuSE.  If it is, I'd file a bug report.

According to wikipedia, SuSE was a slackware translation.  They did adopt
rpm as a package format, but that's about it.

I think the only distro with widespread use that is still like Redhat is
CentOS.  Otherwise, the distro just seems to share rpm as a package format
(e.g. Mandriva) and doesn't have much else in common.
