Problem: :drop tries to :rewind the argumentlist, which results in E37
(after v9.1.0046)
Solution: instead of calling ex_rewind(), call open_buffer() only when
re-using the initial empty buffer

Problem: [security]: overflow in ex address parsing
Solution: Verify that lnum is positive, before substracting from
LONG_MAX
[security]: overflow in ex address parsing
When parsing relative ex addresses one may unintentionally cause an
overflow (because LONG_MAX - lnum will overflow for negative addresses).
So verify that lnum is actually positive before doing the overflow
check.
