Docstring fixes

This is the eighth patch in a series that makes some straightforward
corrections to a number of docstrings.  Each change is normally to:

- correct a typo, or
- fix up hyperlinks to function or variable names, or
- ensure slightly better conformance with the documentation guidelines
  and tips given in the Elisp manual
