Title: clarify documentation for find_input

The docs for find_input say "if $selector is specified" when they mean "if $selector is specified and not undef". And according to the possible calling forms shown, you must always pass a selector.

So my reading of the documentation was that "if $selector is specified" is redundant and you always have to search by selector. Someone else thought they could "not specify" $selector by passing an empty string. This patch tries to clarify that you can pass undef to mean 'any input'.
