My first experience with pywikibot, downloaded core, i wanted to change
a few pages. Immediately ran into an error when trying to set a page's
text to empty. The error message was unhelpful, but I dug through the
source and found the issue. I'd like to suggest that 2 things:
1. Setting a page's text to be empty should be allowed
2. If not, at least the error should be fixed to actually show the
correct error, explained below.
Here is an example script, and the error when running it
import pywikibot
site = pywikibot.Site()
page = pywikibot.Page(site, "MediaWiki:Lastmodifiedat")
page.text = ""
page.save()

This error should be shown instead of the one that is actually shown.
