Good idea; now fixed.

We have the same thing with
forward-sexp: Scan error: "Containing expression ends prematurely", 373, 374
which is pretty cryptic, but `M-f' says
user-error: No next sexp
A general display conversion thing would be nice, but I guess some of
the conversions would be context dependent? The invalid-read-syntax
line/column one wouldn't be, I think...
