New issue 2349 by skr...@gmail.com: Match p**(s-x) for s!=x should return
p=x
http://code.google.com/p/sympy/issues/detail?id=2349
(p**(s-x)).match(1) == {p:1} #for s=Wild('s', exclude=[x])
A first draft patch for this issue is provided (although commented) for
revision and comments in patch for issue 2347.
Only two test fails, one provided by me, and the problem is that this patch
changes the output of simplify (adding minus sign at the beginning) and one
related to the evaluation of an infinite sum in which a division by zero is
raised.
