xinitrc has bit rotted a bit, and needs a housecleaning. There
is very similar code in both 'xinitrc' file and 'Xsession', it
might make sense to either merge the two or have them share a common
portion, or even to have them both generated from a master template
or something at build time, so that there is not code duplication,
and bug fixing needed in two places, but having the risk of only
getting fixed in one place.
I've done quite a bit of cleanups in xinitrc package since filing
this, however it should still have a good review of all scripts
once again to see if there are other ideas to clean things up, such
as some of the ideas Jens had with having an xinput.d dir for the IM
Leaving this open for now.
