Close, but not quite. The default pattern is spec/**/*_spec.rb.

Again, this incorrect. Autotest fires off shell commands that include a list of files to load based on a set of mappings: if file x changes, run a command with file(s) y.

In RSpec, those mappings are defined in Autotest::Rspec2, and they are set to include files that end with _spec.rb, with some additional constraints based on file naming conventions: a change to lib/foo/bar.rb tells RSpec to include spec/foo/bar_spec.rb.

I'm not sure where that's coming from, but it's not default settings of rspec or autotest. What versions of rspec and autotest are you using? Is this a rails app?

Autotest has a mapping mechanism that you can access in its initialize hook. See http://blog.davidchelimsky.net/2008/01/15/rspec-1-1-2-and-zentest-3-8-0/ for more on this.
