thanks for this report
its a default (and obscure) feature of the -last optget()
that breaks the principle of least surprise
(at its worst when it surprises the author)
the next update will have a better default, and your example will work
at issue is a feature that redirects { -number +number } operands
to the first numeric option, e.g., to support the tail(1) shorthands
-2 => -n 2
+2 => -n +2
