Update of /home/cvs/GiNaC/ginac

Modified Files:
	power.cpp relational.cpp 
Log Message:
* Fix a bitch of a bug where 1<I (and all other relationals) returned true.
  This did not happen for the binary relational operators between numerics.
  Now the behaviour is more consistent (throwing exceptions when the difference
  becomes complex).
* Some regression tests were actually wrong in the light of this bug.  :-(
