From: Alexandr Miloslavskiy <alexandr.miloslavskiy@xxxxxxxxxxx> Decisions taken for simplicity: 1) For now, `--pathspec-from-file` is declared incompatible with `--patch`, even when <file> is not `stdin`. Such use case it not really expected. Also, it is harder to support in `git commit`, so I decided to make it incompatible in all places. 2) It is not allowed to pass pathspec in both args and file.
