Including this info is great, thanks.

But, FWIW, I'd much rather that the error object contains "raw data"
rather than "human-readable" data.  I.e. something like:

    xsignal2 (Qinvalid_read_syntax, s, PT);

and then convert the buf-pos to line+column later on, when the error
is displayed.
[ And if we don't have any ready-made place where we can put
  this display-time conversion, then we should probably change that
  as well.  ]
