Log Message:
Update to 1.4.14. From the changelog:

documentation:

* Improve omindex --help docs for --duplicates.
* Document that $log will start to return an error message in 1.5.0, and that
  one can wrap it using a $if with no action now to be future-proof.

indexers:

* Add built-in support for iso-8859-15 so we can handle it without iconv.
  This charset is a variant of iso-8859-1 with 8 characters changed, most
  notably including the euro currency symbol.  It's the most commonly seen
  charset we didn't have built-in support for.
* Optimise converting us-ascii to UTF-8 to do nothing, like we already do when
  converting UTF-8 to UTF-8.
* scriptindex:
  + Add new 'gap' action which provides a way to leave a gap in the term
    positions between fields to prevent phrases and positional operators from
    matching across fields.

omega:

* Fix error handling in $lookup.  We now check for errors from cdb_init()
  and cdb_get().  We've never checked for errors from cdb_init(), while
  for cdb_get() this bug was introduced by a warning fix in 1.2.20.

templates:

* Future-proof use of $log against changes in 1.5.0.
