[python] PR python/10633 (some emitted strings not respecting options->print_max)

As shown in the bug, strings sourced from pretty printers are not
respecting the current length of print_max. This is not a bug with the
pretty printer code itself, but rather a missing check in c-lang.c:c_printstr.

This patch adds a check to the inner loop  while iterating over wchars
to ensure that print_max is observed.

This patch was tested on x86_64 and shows not regressions.

OK?

Regards

Phil
