wp site list doesn't work with domain mapping #669
Description
If you run wp site list with the Wordpress MU Domain Mapping plugin turned on, you'll get the raw URLs in the database.
If you then use one of those URLs in --url=<url>, you'll get a warning:
Warning: Some code is trying to do a URL redirect. Backtrace:
