Right that would be the most consistent and general.
I detailed in the previous mail why I was wary.

It would change the output for df etc. in possibly more
common cases of space and tab used in names.
Maybe that case is uncommon enough to not worry about, but...

more problematically it would change the output from
the lib, so that whereas before any program could unambiguously
access the returned entries directly, now they'd have
to unescape.

seems a bit dangerous to me.

cheers,
Pádraig.
