Fix the following errors in several files.
ERROR: Unexpected indentation.
ERROR: Unknown interpreted text role "paramref".
WARNING: Block quote ends without a blank line; unexpected unindent.
WARNING: Definition list ends without a blank line; unexpected unindent.
WARNING: Enumerated list ends without a blank line; unexpected unindent.
WARNING: Field list ends without a blank line; unexpected unindent.
Specifically the "Unknown interpreted text role" was fixed by adding
a separate import instead of importing 'text' directly. Others were
indentation, new lines, or adding lists.
