* docstrings: fix "Sphinx param with type" pattern
Previously, the pattern only matched if the parameter description
followed on the same line, like so:
:param type foo: A param named foo.
However, it's also valid for the parameter description to be wrapped
onto the next line, like so:
:param type foo:
A param named foo.
This change updates the pattern to match the second example as well, and
adds a test to verify this behaviour.
Fixes#806.
