If there are no groups, it returns a list of strings, where the
strings are the whole match.

If there is one group, it returns a list of strings, where the strings
are the content of the group.

Otherwise, it returns a list of tuples of strings, where the tuples
contain the group contents (the same as if an individual match had its
groups() method called).

If you want consistency, use finditer instead of findall.
