Subject: [PATCH] die_with_status: use "printf '%s\n'", not "echo"
At least GNU echo interprets backslashes in its arguments.
I think that's incorrect in several respects. For one thing, echo is
never called for most Bourne shells since echo is a builtin (might have
been different for UNIX version 7 or so). For another, GNU echo would
behave like Bash:
And GNU Bash does not interpret escapes unless you do echo -e. Escape
sequence interpretation, however, happens for Dash:
dak@lola:/usr/local/tmp/lilypond$ dash -c 'echo "x\tx"'
x x
dak@lola:/usr/local/tmp/lilypond$ bash -c 'echo "x\tx"'
x\tx
dak@lola:/usr/local/tmp/lilypond$ /bin/echo "x\tx"
x\tx
So replace "GNU echo" in your commit message with "Dash's echo builtin"
and you get closer.
