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.
