Hi
Thanks for report.
I've tried to fix them (though differently) since proposed changes
were not always correct.

Here we use a different logic - otherwise we would have a full man page of []
chars.
So ATM whenever there is short & long option format - we are not using []
around them and we just use [] around the whole option.
e.g.:
[-l|--extents ExtentsNumber]
Problems with vgchange.8:
Invalid option format - cannot have optional prefix in token,
it confuses anything trying to do syntactic parsing.

Not really sure what we can do with these - since we have couple other similar
one.
lvm2 does support 'optional' prefix so the user can use shorter variant.
--vgmetadatacopies or just --metadatacopies
--raidmaxrecoveryrate or just --maxrecoveryrate
We can probably just put both option in full form to the list - but this
form --[vg]metadatacopies just looks easier to read and saves space ;)
So are we violating some basic 'man-page-writting' rule - or just the catb
parser is not capable of reading it?
IMHO I've already checked many many other man pages and there is a lot of
different styles - so it's quite unclear how to write it properly.
As of now - page for 'lvcreate.8' is basically the style we are heading to.
(and lot's of pages still needs to be updated).
