git-rebase--interactive.sh: use printf instead of echo to print commit message
On systems with an echo which defaults to the XSI-conformant behavior (Solaris, or others using Ksh), echo will interpret certain backslashed characters as control sequences. This can cause a problem for interactive rebase when it is used to rebase commits whose commit "subject" (the first line) contains any of these backslashed sequences. In this case, echo will substitute the control sequence for the backslashed characters and either the rebased commit message will differ from the original, or the rebase process will fail. Neither is desirable. So work around this issue by replacing the echo statements used to print out portions of the commit message, with printf. Also, add a test to test for this breakage.
