Comment #1 on issue 1461 by [email protected]: cse() failing for a sum
http://code.google.com/p/sympy/issues/detail?id=1461
This was fixed by
commit 80d259755e089fd96824ad3ab9055a16c825432f

cse watches for exact Mul and Add sub-expressions
Adds and Muls that were not repeated subexpressions may still
contain subexpresions that are repeated, e.g. x+y+z and x+y
have x+y in common, but the cse process misses these.
And several tests were added, so I'm not adding this one -- just marking as
fixed.
