That behavior seems fine to me. In your example, Emacs would check
for the following, in-order:

   1. linux2.6.26.el
   2. linux2.6.el
   3. linux2.el

This seems like the right approach - try to match minor versions, but
if there is not a config for a specific minor version, then use the
config that matches the major version.

In this specific instance, it wouldn't actually find anything, because
there is no term/linux2.el file (just a term/linux.el file). This
could be resolved by also splitting between non-numeric characters and
numbers (so we would try linux.el as a step #4), but that's not
necessary to solve my specific problem.
