<p>
HYPHENATE_REFS is a toggle macro; invoking it by itself will turn
automatic hyphenation of REF-bracketed references on (the default).
Invoking it with any other argument (<kbd>OFF</kbd>, <kbd>NO</kbd>,
<kbd>X</kbd>, etc.) will disable automatic hyphenation for
references bracketed by REF.

An alternative to turning reference hyphenation off is to prepend
to selected proper names in your <kbd>refer</kbd> database
