treewide: correct several "up-to-date" to "up to date"

Follow the Oxford style, which says to use "up-to-date" before the noun,
but "up to date" after it. Don't change plumbing (specifically
send-pack.c, but transport.c (git push) also has the same string).

This was produced by grepping for "up-to-date" and "up to date". It
turned out we only had to edit in one direction, removing the hyphens.

Fix a typo in Documentation/git-diff-index.txt while we're there.
