Merge branch 'nd/checkout-noisy-unmerge'

"git checkout [<tree-ish>] <pathspec>" started reporting the number
of paths that have got updated recently, but the same messages were
given when "git checkout -m <pathspec>" to unresolve conflicts that
have just been resolved.  The message now reports these unresolved
paths separately from the paths that are checked out from the index.

* nd/checkout-noisy-unmerge:
checkout: count and print -m paths separately
checkout: update count-checkouts messages
