OK. I've done something similar to the above, however...
If the following command gets passed through "eval" (as noted above), The
backslash in ' printf "\n" ' gets dropped and the 'n' is printed out.
_debug printf "size=%s\n" ${size}
As such, no newline is printed to stdout. If I omit the "eval" command and
just use ${@} (or $"@", "$@", ...) by itself, then the printf interprets the
newline escape (ie. '\n') just fine.
