From 8a98758a8d9dbd807fc2f1576e9141c1b720c5c1 Mon Sep 17 00:00:00 2001 From: Alexandr Miloslavskiy Date: Mon, 17 Feb 2020 17:25:22 +0000 Subject: [PATCH] stash push: support the --pathspec-from-file option Decisions taken for simplicity: 1) For now, `--pathspec-from-file` is declared incompatible with `--patch`, even when is not `-`. Such use case is not really expected. 2) It is not allowed to pass pathspec in both args and file.
