Ugh.  Uhm.  I guess that would probably be too much to factor out,
actually.

If you put a property like that on a function added to
TeX-translate-location-hook, then it gets called with completely
different arguments, and with all errors at once in a list.

This is used in X-Symbol to make it work much much faster with
preview-latex than going by the default translation.

It would not make sense to use this with AUCTeX's current mode of
operation, namely just searching for the next error at any given time.

If we want to fold AUCTeX's manner of operation at one time closer
into comint-mode and normal Emacs error processing, this might become
more relevant.
