Parse legacy -COLUMN and +FIRST[:LAST] forms only as complete arguments before the -- terminator. Preserve option-like filenames after -- and add regression coverage for the affected cases. Fixes uutils#12999

Fixes #12999.
This PR ensures that legacy -COLUMN and +FIRST[:LAST] operands are recognized only as complete arguments before --. As a result, filenames such as a-0 and a-b-0 are no longer misinterpreted as options. Regression tests have been added for the affected cases.
