[lvm-devel] [PATCH 13/15] Man page consistency fixes



Make a better looking colorized manpages for few commands.
It's rather a my proposal how do I'd like to see man pages to be
looking. For view I'm using 'midnight commander' and its colorized
man page reader output looked quite unreabable with original man pages.

Also it removes some common options - they are better described
in lvm(8) page.

This patch makes them IMHO better - but I see it rather for discussion
how the options and options' parameters should be visible.

Also it extends a bit pvremove man page with -ff and -y option
description.
