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

From: Tolga Ceylan <tolga.ceylan@gmail.com>

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
