[lvm-devel] Improve manpage clvmd.8.in

[saulery at free.fr]

Hello,

Following the acceptance of my previous patch after amendment, some changes
have been forgotten. I again proposed, taking into account the comments Zdenek
Kabelac.

Is it deliberate that some tools have long options and not others, or that
options be uppercase, and others lowercase?

I count at least check inconsistencies and omissions on other pages.

Regards,
