ldconfig.8: wfix

* Promote a parenthetical to primary discussion.  64-bit systems are the
  norm nowadays.
* Perform a Kemper notectomy.  That is, stop saying "note that"
  followed by some declarative statement.  This trope is all over Unix
  documentation and I even see it in ISO standards.  The latter doesn't
  serve to recommend it; as Dave Kemper has pointed out, everything we
  put in technical documentation should be worthy of note unless placed
  in a footnote, marked as "unnecessary on a first reading", or similar.
  It is the exception, not the rule.  If you feel the need to say "note
  that", consider what adjacent material you shouldn't be saying at all.
* Say "symbolic link" instead of "symlink".
* When one sentence explains the previous, use a semicolon.
* Place the modifier "only" more carefully.
* Recast option descriptions to be in the imperative mood.
* Recast file descriptions to use the paragraph tag as the subject of
  the first sentence.
