The documentation says that only empty items at the start and end are
dropped, thus the result should be ["", "", "x", "", ""].
But I can see you would like to drop all empty items. Or all empty
items at the start and end.
So far the keepempty argument was zero or non-zero. If we make it a
string then we can pass different flags:
0 default - drop empty items at start and end
1 keep all empty items
'd' drop all empty items
's' drop one empty item at start
'e' drop one empty item at end
'se' drop one empty item at start and end
How about that?
