Prevent panic when split is called but the msgstore is either not initialized or has no UIDs. This condition could be triggered by calling :split or :vsplit immediately at startup. Use the same logic as the :view command, which could operate in a similar manner. Signed-off-by: Tim Culverhouse <tim@timculverhouse.com> Acked-by: Robin Jarry <robin@jarry.cc>
