Comment (by nbruin):
Actually, these variables are very easy to recognize any way:
{{{
sage: function('f',x)
f(x)
sage: var('c')
c
sage: W=diff(f(x),x,x)-f(x)+c
sage: V=diff(f(x),x)-f(x)+c
sage: maxima_calculus(V).ode2(f(x),x)
'f(x)=(c*%e^-x+%c)*%e^x
sage: maxima_calculus(W).ode2(f(x),x)
'f(x)=%k1*%e^x+%k2*%e^-x+c
}}}
As you can see, maxima creates these constants as `%c, %k1, %k2`, so
there's no collision there. The collision only happens upon conversion
back to sage. So we make the conversion more intelligent there wouldn't be
an issue at all. Using `sage.interfaces.maxima_lib.max_to_sr` this would
be fairly straightforward.
