This will no longer work with the current state of things, as
$TOPDIR/.version keeps increasing.

These are completely different types of IDs. The .version number is a
local build ID and changes when one applies a local patch, or simply
changes a config option, and recompiles his/her kernel. The git ID of
course doesn't.

something many people are interested in, so we can't just drop it.
