Security fix:
The function print_encode() is used both for plain text
and for quoted attribute values.
Escape the '"' character such that malicious manuals cannot pull off
XSS attacks using malformed .Lk, .Mt, .%U, and .UR macros (and maybe
others) to trigger the latter case.
In the former case, escaping does no harm.
