The tcsh with RedHat 6.1 is 6.08. The current version of
tcsh is 6.09. tcsh 6.09 was released on August 16, 1999.
Among other things, it fixes a minor bug annoying y2k bug
involoving incorrect years being printed in the prompt in
2000 and later. (2000 through 2009 print as 10, 2010
through 2019 print as 11, etc.)
For what it's worth, the tcsh 6.09 distribution's README file says it
is 6.08. If you package this, you may want to include a patch so that
/usr/doc/tcsh-6.09.00 doesn't contain confusing files that will
generate false bug reports....
bug id 6000 is related to this. a new version beyond 6.09 fixes a globbing bug
outside of the C locale.
