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. Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
