From a56c8f5aab5a6ffdd687de5134883df60cc4c919 Mon Sep 17 00:00:00 2001 From: Aaron M Watson Date: Mon, 24 Oct 2016 19:40:13 -0400 Subject: [PATCH] stash: allow stashes to be referenced by index only MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Instead of referencing "stash@{n}" explicitly, make it possible to simply reference as "n". Most users only reference stashes by their position in the stash stack (what I refer to as the "index" here). The syntax for the typical stash (stash@{n}) is slightly annoying and easy to forget, and sometimes difficult to escape properly in a script. Because of this the capability to do things with the stash by simply referencing the index is desirable. This patch includes the superior implementation provided by Øsse Walle (thanks for that), with a slight change to fix a broken test in the test suite. I also merged the test scripts as suggested by Jeff King, and un-wrapped the documentation as suggested by Junio Hamano.
