Make "local" orthogonal to date format

Since version 2 there are four new preparatory patches which remove lists of date formats from documentation in favour of referring to the detailed list in git-rev-list(1) or git-log(1) (both generated from Documentation/rev-list-options.txt) depending on whether the page in question is plumbing/porcelain.

I've also reordered the test cleanup patches earlier so that the test for "--date=raw" is added before the new patch that moves "local" processing before the "raw" case. The tests also now wrap long lines and a missing "&&" has been added.

In patch 7 (date: check for "local" before anything else), we no longer reject "relative-local" and "raw-local" now prints the user's local timezone offset. The error message for invalid formats that are prefixed with a valid format name is now the same as that if there is no valid prefix.
