[PATCH 4/7] man: sync "PARAMETER TYPES" section with HOWTO

[kusumi.tomohiro@gmail.com]

From: Tomohiro Kusumi <tkusumi@tuxera.com>

This commit brings in updates from HOWTO to man page. As a result it
replaces some entire paragraphs with the corresponding ones in HOWTO,
though not much difference for the replaced part as it only had small
modification basically saying the same thing.
