RENUMBER 200,10,10-99

fails with Can't Continue Error.

The reason is unclear. A user might accept that RENUMBER has certain restrictions to prevent it from, say, deleting a line accidentally. And perhaps a user could understand that RENUMBER can't interleave new lines with old ones. But this command is just trying to move a region of lines to the end of the program, which seems like a common use case.

Using an unbounded range works (10-) works, but this is just renumbering everything, not reordering anything. If RENUMBER is incapable of reordering lines, we should at least document this, or rewrite RENUMBER entirely to be more useful.

RENUMBER 50,10,10-99 works, but this request does not reorder the lines.

The command is called RENUMBER, not REARRANGE! ;-)
