Description Chris Bradfield 2017-09-11 05:26:25 UTC 
Recent builds of csh/tcsh have a bug where entering a symlink does not honor the logical path. Instead, it adopts the physical path:

% cd /tmp
% ln -s /usr/local .
% cd local
% pwd
/usr/local
% cd ..
% pwd
/usr

Contrast this with sh:
$ cd /tmp
$ cd local
$ pwd
/tmp/local
$ cd ..
$ pwd
/tmp

This behavior started in the last 3-6 months I would guess.
