Comment #2 on issue 2077 by asmeurer: classify_ode() doesn't catch a
1st_linear/separable ode

I bisected it down to this commit in your branch:

1811: separatevars and gcdfactor
separatevars, coef_resid, agcd, _rgcd
gcd_methods
matrices uses gcdfactor
trigsimp uses gcdfactor
The legacy trigsimp_nonrecursive is renamed (as in other
places in sympy) _trigsimp and its docstring was moved to
trigsimp. In addition, gcdfactor is used to factor out
terms that would otherwise not be detected by patterns and
a docstring testing this is added.
integral uses gcdfactor
separatevars and factor-nc
functions added to iterables
Obviously, you made some improvement to separatevars() that makes it
recognize this one now. Actually, I never ever noticed that this equation
was separable too. That would have been useful to know whenever I solved
this one in my homework assignment :)
