mq: qdiff with the same diff options than qrefresh (issue1350) Specifically, if current patch is a git patch and mq.git=keep, diff in git mode.

mq: upgrade to git patch when necessary (issue767)

patch: support diff data loss detection and upgrade In worst case, generating diff in upgrade mode can be two times more expensive than generating it in git mode directly: we may have to regenerate the whole diff again whenever a git feature is detected. Also, the first diff attempt is completely buffered instead of being streamed. That said, even without having profiled it yet, I am convinced we can fast-path the upgrade mode if necessary were it to be used in regular diff commands, and not only in mq where avoiding data loss is worth the price.

mq: preserve --git flag when folding patches Without this, folding a git patch into a regular one downgrades the resulting patch to a regular patch.

mq: preserve --git flag when merging patches Without this, merging a patch queue without diff.git=1 downgrades all git patches to regular patches, losing data in the process.

mq: stop caching and sharing diff options Several mq commands mutate the shared options which causes hard to track bugs when multiple calls are combined.
