Merge "Fix and be more explicit about plurals best practices."

<p>The selection of which string to use is made solely based on grammatical <i>necessity</i>.

In English, a string for <code>zero</code> will be ignored even if the quantity is 0, because 0

isn't grammatically different from 2, or any other number except 1 ("zero books", "one book",

"two books", and so on).

"two books", and so on). Conversely, in Korean <i>only</i> the <code>other</code> string will

ever be used.

<p>Don't be misled either by the fact that, say, <code>two</code> sounds like it could only apply to

the quantity 2: a language may require that 2, 12, 102 (and so on) are all treated like one

             As a developer, you should always supply "one" and "other"

             strings. Your translators will know which strings are actually

             needed for their language. Always include %d in "one" because
