Greg NISBET 077eee8f86 [shell] Override CDPATH in brew script. ...

The CDPATH environment variable can affect the behavior of
`cd`, and `cd` takes the `-P`, `-L` and `-e` flags.
(I didn't know about `-e` until looking at the source)
Make quietcd more robust by setting the CDPATH to ''.

I tested this change by running the following commands from a nonstandard
directory, which caused some of tcsh's and perl's dependencies to be recompiled.

$ [path to brew] install tcsh
$ [path to brew] install perl

Here's a link to the source code of `cd` in a mirror of the bash repo.
