[PATCH] Correct some docstrings [part 2]

[Philip Rooke <phil@yax.org.uk>]

This is a second 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

No attempt is made to provide missing docstrings or document arguments.

Cheers,

Phil
