There is no way to make Diff Patch contain any binary deltas

Reproduction steps

use Diff.Compare to create a patch that contains BinaryComparisons
save this patch to a file patch.file
call git apply with the created patch.file

Expected behavior

there should be a user settable CompareOption that gives access to the GIT_DIFF_SHOW_BINARY flag in Core.GitDiff.GitDiffOptionFlags so that a patch can be created with binary deltas so that binaries are created/updated in the repo after calling git apply patch.file

Actual behavior

there is no option to set this flag so binaries are not created and or not updated by the patch file

まず Diff.Compare と CompareOption を Core.GitDiff.GitDiffOptionFlags まで追跡し、既存の flags がどのように公開されているかに注目します。BinaryComparisons を使用して patch を作成し、git apply で適用して変更を確認します。patch にバイナリデルタが含まれ、バイナリが作成または更新されれば完了です。
