Revert 1.4, that just trades one problem for a different one
(splitting the message on % instead of white space, which affects
less messages, but makes a bigger mess of them when it happens).

The real problem is that the expansion of the message was unquoted,
which allowed the field splitting to happen at all (which was mitigated
by the way printf rescans its format string for each arg when there are
more args than conversions in the format) otherwise it would have been
a much bigger mess (both times).

Just add quotes where quotes are needed, no more splitting, all good.
