** MOVE UNDER WARP POWER
**
** This is both the "move" and the "ram" commands, differing
** only in the flag 'fl'. It is also used for automatic
** emergency override mode, when 'fl' is < 0 and 'c' and 'd'
** are the course and distance to be moved. If 'fl' >= 0,
** the course and distance are asked of the captain.
**
** The guts of this routine are in the routine move(), which
** is shared with impulse(). Also, the working part of this
** routine is very small; the rest is to handle the slight chance
** that you may be moving at some riduculous speed. In that
** case, there is code to handle time warps, etc.
