[PATCH] die_with_status: use "printf '%s\n'", not "echo"

At least GNU echo interprets backslashes in its arguments.

This triggered at least one bug: the error message of "rebase -i" was turning \t in commit messages into actual tabulations. There may be others.

Using "printf '%s\n'" instead avoids this bad behavior, and is the form used by the "say" function.
