The docs for BasePage.get() say:
pywikibot.exceptions.IsRedirectPageError – The page is a redirect. The argument of the exception is the title of the page it redirects to.
but that doesn't seem to be what's actually happening:
> from pywikibot import Site, Page
> from pywikibot.exceptions import IsRedirectPageError
>
> site = Site("en")
>
> page = Page(site, "Template:shortdescription")
> try:
> print(page.get())
> except IsRedirectPageError as ex:
> print(f"{ex.args=}")
prints
> ex.args=(Page('Template:Shortdescription'),)
Am I just not understanding the doc correctly?
