Subject: mandoc: Input lines that are not blank but generate no output, for 
X-Mailer: activitymail 1.26, http://search.cpan.org/dist/activitymail/

Log Message:
-----------
Input lines that are not blank but generate no output,
for example lines containing nothing but "\&", are significant
in no-fill mode and can be represented by blank lines inside <pre>.
Fixing a bug that Pali dot Rohar at gmail dot com found
in pod2man(1) output, for example Email::Address::XS(3p).

While here, inside no-fill mode, there is no need to encode
totally blank input lines by emulating .PP - just let them
through as we are inside <pre> anyway.
