Fix bug [2874237] monster info display corruption

Examining monsters with ctrl-X can lead to message corruption if the
title and body fields of the describe_info struct used by
process_description take up lines than fit in the message area.

This patch avoid the problem by allowing process_description to print
just the title field if title + body would take up too many lines.

Also make view_desc_proc start one line later since it seemed to be
trying to print the first line it was given one line above where it
should have been.
