Details

Description:
/etc/csh.cshrc forces the creation of a .tcsh.config in the user's home for setting certain environment variables, e.g. TCSH_SHELL_CTRLD, that are not actually used by tcsh. tcsh does not use environment variables for configuration, rather it has its own "shell variables" to avoid polluting the environment, and tcsh's manpage does not mention these environment variables. As far as I can tell, they are not read by any of the configuration scripts either, except for one mention of TCSH_SHELL_COMPLETION in csh.cshrc. This code is all unneccessary and I think is left over from when the scripts used to work differently (maybe only in Gentoo, where they came from).

This is not an upstream problem, the tarball from tcsh.org doesn't mention these environment variables (grep -r) and doesn't include csh.cshrc (except for cygwin).

How to fix:
apply my patch to csh.cshrc (attached).
remove /etc/skel/.tcsh.config

Additional info:
extra/tcsh 6.16.00-3

Steps to reproduce:
less /etc/csh.cshrc
or launch tcsh as a new user and see the message about the creation of .tcsh.config.
