I'm just starting to use pywikibot. I see that many of the methods of site have an optional "total" argument. In some places, it's documented as:

if not None, limit the generator to yielding this many items in total

In other methods, it just says:

number of pages to return

In some methods, such as allpages(), it's not documented at all. Is it safe to assume that anyplace total appears, it has the first meaning, i.e. if I pass in None, there's no limit?
