log -L: fix overlapping input ranges

The existing code was too defensive, and would trigger the assert in
range_set_append() if the user gave overlapping ranges.

The intent was always to define overlapping ranges as just the union
of all of them, as evidenced by the call to sort_and_merge_range_set().
(Which was already used, unlike what the comment said.)

Fix by splitting out the meat of range_set_append() to a new _unsafe()
function that lacks the paranoia.  sort_and_merge_range_set will fix
up the ranges, so we don't need the checks there.
