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

[Phillip Wood <phillip.wood@talktalk.net>]

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
