Yes.  I originally thought of "^.git" to mirror regexps, but not to implement regexps for the reason you state.

I like your idea better, given that it really isn't a regexp.

The only (minor) issue I see is the name of the customization variable - at that point, the string no longer represents an extension of the file name.  Perhaps we'd argue that it's an extension (suffix) of the whole path name.

We might want to go through the default set of extension and update it.  "/.bzr/", for instance, and the other VCS directories. 

BTW, this functionality as well as the Emacs 23 completion mechanism are very well conceived and quite useful!
