17739 enhance desolve output from separable ODEs rws "At the moment, `desolve` behaves like this even with trivial separable ODEs:
{{{
sage: t = var('t')
sage: y=function('y')(t)
sage: desolve(diff(y,t)-y^2,y)
-1/y(t) == _C + t
sage: desolve(diff(y,t)-y^2+y,y)
log(y(t) - 1) - log(y(t)) == _C + t
sage: desolve(diff(y,t)-y^2-1,y)
arctan(y(t)) == _C + t
}}}
They could be solved by substituting a variable for `y(t)` and calling `solve`. Only if there is no solution from `solve` the integrated equation should be given.
