Subject: git-p4: format-patch to diff-tree change breaks binary patches
X-Git-Tag: v1.9.3~3^2

git-p4: format-patch to diff-tree change breaks binary patches

When applying binary patches a full index is required. format-patch
already handles this, but diff-tree needs '--full-index' argument
to always output full index. When git-p4 runs git-apply to test
the patch, git-apply rejects the patch due to abbreviated blob
object names. This is the error message git-apply emits in this
case:

    error: cannot apply binary patch to '<filename>' without full index line
    error: <filename>: patch does not apply
