Bug with $cwd in 4.2BSD csh

[Danny Glasser]

    Here's an interesting 4.2BSD csh bug:

	Let's say that /foo/lib/bar is a soft link to /usr/lib/bar (which is
a directory), where /foo/lib and /usr/lib are distinct directories.  I say
the following:

	% cd /foo/lib/bar
	% pwd
	/usr/lib/bar
	% echo $cwd
	/foo/lib/bar
	% cd ..
	% pwd
	/usr/lib
	% echo $cwd
	/foo/lib

    Note that the "cwd" shell variable is not set properly.  The problem
is with the differing notions of what the parent directory is.

    [If this bug has already been reported and I missed it, I apologize
for rebroadcasting it.]
