character -> characters?

I guess the comment should say "see set print characters N".

We would need a corresponding doc update for this, in python.texi.

Maxiumum -> Maximum.  End with a period + 2 spaces.

> +  unsigned int print_smax;

I would suggest using a clearer name, like print_max_chars.

Although Eli raised a good question, do we limit the number bytes of
characters?  What would happen if we print a wide char or UTF-8 string?
