Support `--patience` flag of `diff-tree` command

[dmalikov]

Currently Diff.Compare<Patch> method doesn't support --patience flag, thus it's impossible to implement git command like that using the library:

git diff-tree T1 T2 --patience

The flags are binded here.

I guess it's just a matter of exposing this data in CompareOptions

Indeed!

Labeled as up-for grabs.

@nulltoken could you please explain a little bit what does "up-for-grabs" label actually mean?

@dmalikov The idea behind that label comes from here:

@dmalikov This means that we would be interested in exposing this feature but, as it doesn't require a strong expertise to make it happen, core contributors will refrain from implementing it.

Indeed, it may be an easy first task for a new contributor willing to dabble with the library and we would happily support him/her until the feature's ready to be merged.
