This is not a disclaimer, but an explanation of the relationship
between pydoc pages and the reference manual.

docloc should not be None for standard library modules.  This is a
separate issue.

In text viewer you only see one page at a time.  In HTML you may put
it on the index or start page.

docloc is None for 3rd party modules (pydocs checks for site-packages
component in path).  The logic is not very robust, but that is a
separate issue.

That's fine.

No, these places are almost never seen.  Also, one should not think of
this as a disclaimer, but as an explanation of why she is shown a link
to a reference page when full documentation is already displayed.

Sure.   Just don't call it "disclaimer".  Maybe Doc.REFTEXT constant
next to Doc.PYTHONDOCS?
