mandoc: Improve "man -h" output.

[schwarze@mandoc.bsd.lv]

Log Message:
-----------
Improve "man -h" output.
1. For pages lacking a SYNOPSIS, show the NAME section rather than nothing.
2. Do not print a stray blank before the beginning of a SYNOPSIS.
Both issues reported by, and patch OK'ed by, tb@.
