[issue16082] xml.etree.ElementTree.tostringlist does conform to it's documentation

[Einar Fløystad Dørum]

New submission from Einar Fløystad Dørum:

The tostringlist documentation says "Returns a list of (optionally) encoded strings containing the XML data. It does not guarantee any specific sequence, except that "".join(tostringlist(element)) == tostring(element).". 
But in reality it is possible to get tostringlist to return a string and not a list. 
The following code will demonstrates problem, by failing with a TypeError:

from xml.etree.ElementTree import Element, tostringlist, tostring

element = Element("foo")
print ("".join(tostringlist(element)) == tostring(element))
