conditional in in _parse_rfc meant to error when "empty property name", can't ever trigger

[drocta]

In the method _parse_rfc, lines 1668-1670 of rrule.py (as of commit da9ecd0 , the latest to touch that file as of this writing (not that it changed these particular lines)) read:

                parms = name.split(';')
                if not parms:
                    raise ValueError("empty property name")

Where name is a string. parms here will therefore always be a list of one or more strings. Such a list is never false-y, even if the only entry is the empty string.
It looks to me like that conditional is meant to be checking if the string line looks like ;PARM1;PARM2:MORESTUFF rather than like PROPERTYNAME;PARM1;PARM2:MORESTUFF or PROPERTYNAME:MORESTUFF or etc.
As such, I think the conditional should read, if not parms[0]: instead?
As is, the only way I can see this condition triggering is if name was of some type other than str, such that name.split(';') might return something other than a list of one or more strings.

(If I'm wrong about all this, sorry. I think I'm right though?)
