/*
 * Comments about the restructuring of the old breaks() routine.
 *
 * There are now three distinct phases to object breaking:
 *     breaktest() - which makes the check/decision about whether the
 *                   object is going to break.
 *     breakmsg()  - which outputs a message about the breakage,
 *                   appropriate for that particular object. Should
 *                   only be called after a positive breaktest().
 *                   on the object and, if it going to be called,
 *                   it must be called before calling breakobj().
 *                   Calling breakmsg() is optional.
 *     breakobj()  - which actually does the breakage and the side-effects
 *                   of breaking that particular object. This should
 *                   only be called after a positive breaktest() on the
 *                   object.
 *
 * Each of the above routines is currently static to this source module.
 * There are two routines callable from outside this source module which
 * perform the routines above in the correct sequence.
 *
 *   hero_breaks() - called when an object is to be broken as a result
 *                   of something that the hero has done. (throwing it,
 *                   kicking it, etc.)
 *   breaks()      - called when an object is to be broken for some
 *                   reason other than the hero doing something to it.
