"Partial Path" cd

[Mark Johnson]

I wrote up some code to do "partial prefix" cd if the argument to cd is
not valid.  (If some one has a better phrase I'd be glad to hear it).

An example:

$ cd /usr/local/TEST.txt 
bash: cd: /usr/local/TEST.txt: Not a directory
$ shopt -s cdpartial
$ cd /usr/local/TEST.txt 
/usr/local
$ pwd
/usr/local
$

I tend to do this a lot after editing a file (vi .../README) and then 
want to change to the directory that had that file in it, so I type
cd ESC-. RET so bash tries to cd /usr/local/README.

So the question is, for Chet especially, is this wanted in Bash?

I did realize (afterwards: doh!) that this could be done with a function,
but after also coding up the shell function I feel the C approach is
cleaner.
