Old description:
> solve() raises an index error on empty solutions if solution dictionary
> was requested; returns empty list instead of empty dictionary in other
> cases.
New description:
{{{solve()}}} raises an {{{IndexError}}} on empty solutions if a list of
solution ''dictionaries'' is requested.
The description/examples may mislead w.r.t. the result type.

Comment:
Sorry, unable to delete the previous patches; '''apply only the last
one'''.
* {{{IndexError}}} issue fixed.
* Type of parameter {{{solution_dict}}} relaxed as suggested by Mike
Hansen (now consistent; also in
{{{expression.pyx}}}/{{{Expression.solve()}}}).
* (More) Doctests added.
* Description made more clear. Some typos fixed.
