A number of small fixes.  Most were to fix minor bugs in string and
TeX output, particulary for the various list-based objects (like
vectors, intervals, etc.).  There were also some bug fixes in the
comparison routines.  Some additional checks were added for valid
intervals when the coordinates are formulas.
