Help for max size

[Thomas Applencourt]

Reported by Marta:

--max-name-size Maximun size allowed for names
so I assumed there was a default size by default and a max. size set while activating that.
Maybe it would be good to add something like this (btw, there is a typo in the last letter of maximummmmm:
--max-name-size Maximun size allowed for names (default XXX characters), e.g. --max-nam-size 1000

As of now, XXX = 80 characters
