The editors I know of (LEdit and LDAO) don't automatically update moved
parts. But it is a good idea that they should do so. I'm adding it to
my list of suggestions.

It seems like someone (Lars? Tore? Leo?) wrote a program that would
update the moved parts in all files from ldraw\models.
Doing this automatically as part of a parts update install would be
great.

Difficult? Maybe. Actually, if self-extracting ARJ files[1] can be
configured to launch another program after extracting, we should be able
to do this fairly easily.
Now, to correctly update models in updates where a new part overwrites
and old part (which is being move at the same time), things get a little
more interesting:
Step 1. Install old part with new number, and a "~moved to" stub file.
Step 2. Run model updater utility.
Step 3. Extract new part over old part's "~moved to" stub file.
This could be done with self-extracting/launching program, but the files
for step 3 would have to be in a sub-archive, which is also
self-extracting.
