In clap v3, `require_value_delimiter` activated an alternative parse
mode where
- `multiple_values` meant "multiple values within a single arg"
- `number_of_values` having no parse impact, only validation impact
- `value_names` being delimited values
For unbounded `number_of_values`, this is exactly what `value_delimiter`
provides. The only value is if someone wanted `value_name` to be
`<file1>,<file2>,...` which can be useful and we might look into adding
back in.
Alternatively, this could be used for cases like key-value pairs but
that has issues like not allowing the delimiter in the value which might
be ok in some cases but not others. We already instead document that
people should instead use `ValueParser` for this case.
In removing this, we remove points of confusion at how the different
multiple values and delimited value calls interact with each other. I
know I would set `require_value_delimiter(true).multiple_values(true)`
when it turns out all I needed was `value_delimiter(',')`.
This also reduces the API surface area which makes it easier to discover
what features we do provide.
While this isn't big, this is also yet another small step towards
reducing binary size and compile times.
