PATCH Re: 5.3: printf -

[Bart Schaefer <schaefer@xxxxxxxxxxxxxxxx>]

Apparently this was introduced in 37467 when I changed "printf" from
having no options at all to having the -v option for print-to-variable.

There's some documentation saying that ideally we would not create any
new builtins with BINF_SKIPINVALID but I don't see any other way to get
back the old behavior.
