Function get_wormno

src/worm.c:95–106

* get_wormno() * * Find an unused worm tail slot and return the index. A zero means that * there are no slots available. This means that the worm head can exist, * it just cannot ever grow a tail. * * It, also, means that there is an optimization to made. The [0] positions * of the arrays are never used. Meaning, we really *could* have one more * tailed worm on the level, or use

 *  Implementation is left to the interested hacker.
