Bug#698615: lp ignores silly options; should give error

["Trent W. Buck" <trentbuck@gmail.com>]

Package: cups-client
Version: 1.5.3-2.12
Severity: wishlist
Tags: upstream

While dealing with an unrelated issue, I tried to type

    date | lp -n2 -o collate=true

but instead I typed

    date | lp -n2 --collate=true

AFAICT, lp silently ignored the bogus option.
I would strongly prefer that it instead gave an error like this,
possibly followed by a help synopsis of valid options.

    lp: illegal option -- -

In this case, because I didn't notice the typo, I ended up wasting a
couple of hours trying to debug the pxlmono.ppd that (I thought)
wasn't working as advertised :-(
