[PATCH/RFC] t3404: test autosquash for fixup! commits with funny messages

[Uwe Storbeck <uwe@ibr.ch>]

This commit adds a test to verify the correct behavior when
rebase -i is used to autosquash fixup! commits where the commit
message contains a backslash sequence (\n).

When echo is used instead of printf to handle such a commit
message the test will fail on shells (e.g. dash) where the echo
command interprets backslash sequences as control characters.
