Until the attribute layer is usable everywhere ;-)

A valid reason not to put the index on the volume is with multiuser,
and read-only volumes (even though layers could work around this).
One should still be able to index non user writable volumes this way...

Another reason is to avoid conflicts with other users or different
machines with different indexing settings, where each would overwrite
the index each time to fit its own settings.

It could also be made configurable.

We'll also want to not index stuff like .svn/* and others... or not as
text at least.
