Thanks for sending - sorry about the delay, this got lost on me. This is
one of those sharp edges of shell where I'm not really sure of the 'best'
solution. Do you know of any doc on ansi-c quoting and best practices
as described? E.g. is this method you sent commonly prescribed somewhere?

Curious - would `xargs -d"\\n"` work alternatively for you?
