[Configobj-develop] string_list validator supporting single item lists?

[Darren S. <pha...@gm...>]

Greetings,

I have a field in my configuration section that should be set with a
list of one or more email addresses for notification; i.e. either of
these configuration settings would be correct:

notify = me...@ex...

notify = me...@ex..., yo...@ex...

What seems ideal would be for the string_list() validator to accept a
single list item (essentially, the same validation as string()) and
not *only* a list. I sampled it with a 'min' value of 1 but that also
resulted in validation failure with a single value in the field:

notify = string_list(default=None, min=1)

Is there a way to accomplish this with the string_list() validator, or
does this require a custom validator? Any chance to see a modification
string_list to support single-item lists if not?
