Re: [PATCH 2/3] rebase: Add tests for console output

> From: Phillip Wood <phillip.wood@dunelm.org.uk>
> 
> Check the console output when using --autostash and the stash applies
> cleanly is what we expect. To avoid this test depending on commit and
> stash hashes it uses sed to replace them with XXX. The sed script also
> replaces carriage returns in the output with '\r' to avoid embedded
> '^M's in the expected output files. Unfortunately this means we still
> end up with an embedded '^M' in the sed script which may not be
> preserved when sending this. The last line of the sed script should be
> +s/^M/\\r/g
