cherry-pick/revert: add support for -X/--strategy-option
For example, this would allow cherry-picking or reverting patches from
a piece of history with a different end-of-line style, like so:
$ git revert -Xrenormalize old-problematic-commit
Currently that is possible with manual use of merge-recursive but the
cherry-pick/revert porcelain does not expose the functionality.
While at it, document the existing support for --strategy.
