Subject: [PATCH] revisions --stdin: accept CRLF line terminators

From: Johannes Sixt <[email-masked]>
Date: Tue, 11 Aug 2015 22:21:33 +0200

On Windows, 'git rebase -i' with rebase.missingCommitsCheck set to
warn or error reports:

   Dropped commits (newer to older):
   'atal: bad revision '410dee56...

The error comes from the git rev-list --stdin invocation in
git-rebase--interactive.sh (function check_todo_list). It is caused by
CRs that end up in the file "$todo".miss, because many tools of the MSYS
toolset force LF to CRLF conversion when regular files are written via
stdout.

To fix the error, permit CRLF line terminators when revisions and
pathspec are read using the --stdin option.

 This fixes a new failure in the test suite (t3404.8[67]) on Windows, but
 I got around to debug it only now.
