   5:  * append:  append a tail to a list of roots or prepend a head to a list
   6:  *	    of tails.
   7:  * use:
   8:  *	append tail root1 root2 ... rootn
   9:  * result:
  10:  *	root1tail root2tail ... rootntail
  11:  * or
  12:  * 	append -p root tail1 tail2 ... tailn
  13:  *  result:
  14:  *    	roottail1 roottail2 ... roottailn
  15:  *
  16:  * or
  17:  *	append -s xtail root1xoldt root2xoldt ...
  18:  *  result:
  19:  *	root1xtail  root2xtail ...
  20:  *   that is, each root is tested for the presence of 'x', the first character
  21:  *   in the tail.  If it is present, then all characters beyond it are thrown
  22:  *   away before merging.  This is useful for things like
  23:  *	append -s .c foo.o bar.o baz.o =>> foo.c bar.c baz.c
  24:  *
  25:  * Useful in Makefiles due to the lack of such facilities in make.
