New issue 2900 by smi...@gmail.com: xreplace rebuilds expressions when
there is no rule
http://code.google.com/p/sympy/issues/detail?id=2900
I'm not sure that xreplace should do anything to an expression if the rule
is empty, hence foo.xreplace({}) should return foo. (If foo is unevaluated,
it becomes evaluated if xreplace({}) is applied to it.)
I've made a commit making it return foo unchanged in
https://github.com/sympy/sympy/pull/824
