No support for empty string options?

[sthibaul]

In speech dispatcher, we use string options which can have an empty value, which we write "". It seems that dotconf doesn't support it:

GenericPunctNone ""

yields to

Missing argument to option 'GenericPunctNone'

Is

return buf[0] ? strdup(buf) : NULL;

really on purpose? That prevents from being able to pass empty string, is there really a use case for doing this?
