The default behaviour of tcsh has significantly changed starting from
version 6.14-r1. In contrast to previous ebuilds, the amount of
customisation to the default shell's behaviour has been reduced to a
bare minimum (a customised prompt).
If you rely on the customisations provided by previous ebuilds, you will
have to copy over the relevant (now commented out) parts to your own
~/.tcshrc. Please check all tcsh-* files in
/usr/share/doc/${P}/examples/ and include their behaviour in your own
configuration files.
The tcsh-complete file is not any longer sourced by the default system
scripts.
