[PATCH 2/2] git-rebase--interactive.sh: use printf instead of echo to print commit message

[Brandon Casey <casey@nrlssc.navy.mil>]

From: Brandon Casey <drafnel@gmail.com>

Replace the echo statements that operate on $rest with printf's to restore
what was lost from 938791cd.  This avoids any mangling that XSI-conformant
echo's may introduce.

Junio,

Feel free to squash this into 1/2 if desired.
