String formatting of the message was broken by #76 (`s.format()` needs
separate arguments, not a tuple, as opposed to `s % ()`.

We also prettify the message by creating a comma-separated list of
aliases.

For example, CLN3 in Dog doesn't have NomenclatureSymbol set, but it
does have Name.

Remember optional argument for dup during parsing

This enables checking the argument of a dup variant, e.g., checking if
the `T` in `g.45dupT` is correct.
