I'm not sure why you would encounter code like that in the first place. Surely any code of the form:

''.join(c for c in mystring) would just return mystring? Or am I missing something?

Good question. Anything useful like "'-'.join(c for c in 'abc')" is the same as "'-'.join('abc'). The same, as far as I can think of, for anything like list() or set() taking an iterable arg.
