I installed the patch (including a comment in the docstring for
bibtex-autokey-titleword-ignore that case is significant.)

Package: emacs
Version: 23.0.90.1

I'm taking the liberty to forward the following bug from the Ubuntu
Launchpad:

https://bugs.launchpad.net/ubuntu/+source/emacs22/+bug/243156

> What I Expected to Happen
> ====================
> 
> This affects the BibTeX mode. Emacs 20 changed the behaviour, thus:
> 
> *** Autokey generation now uses all words from the title, not just
> capitalized words. To avoid conflicts with existing customizations,
> bibtex-autokey-titleword-ignore is set up such that words starting 
> with lowerkey characters will still be ignored. Thus, if you want to 
> use lowercase words from the title, you will have to overwrite the 
> bibtex-autokey-titleword-ignore standard setting.

If this were a real .signature, it would suck less.  Well, maybe not.
