`pariErr` like we already do for `pariOut`? Besides not having to patch
PARI to add another callback, this has the additional advantage that the
error text can be stored for possible inspection.

the printing of an extra newline in `err_init()` and the use of ANSI
escape sequences for colours.
I see. But wouldn't it be a more satisfactory solution to have PARI do
those things only if the output is connected to a terminal (using
`isatty`)? This would still require a patch, of course.
