check mincopies is satisfied even when numcopies is known to be satisfied

I had been assuming that numcopies would be a larger or at most equal to
mincopies, so no need to check both. But users get confused and use configs
that don't really make sense, so make sure to handle mincopies being larger
than numcopies.

Also add something to the mincopies man page to discourage this
misconfiguration.

@ -25,6 +25,12 @@ repositories, git-annex may violate the numcopies setting.
In these unusual situations, git-annex ensures that the number of copies
never goes below mincopies.
It is a good idea to not only rely on only setting mincopies. Set
numcopies as well, to a larger number, and keep mincopies at the
bare minimum you're comfortable with. Setting mincopies to a large
number, rather than setting numcopies will in some cases prevent
droping content in entirely safe situations.
