From 39743cf554caaed462464b55315ab5b37f5ab1b9 Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Wed, 28 Oct 2015 15:54:48 +0100 Subject: [PATCH] rebase-i: work around Windows CRLF line endings Editors on Windows can and do save text files with CRLF line endings, which is the convention on the platform. We are seeing reports that the "read" command in a port of bash to the environment however does not strip the CRLF at the end, not adjusting for the same convention on the platform. This breaks the recently added sanity checks for the insn sheet fed to "rebase -i"; instead of an empty line (hence nothing in $command), the script was getting a lone CR in there. Special case a lone CR and treat it the same way as an empty line to work this around. This patch (also) passes the test with Git for Windows, where the issue was seen first.
