Problem:
The Vim "stuff" concept breaks the ability to reason about the call
stack and thus the boundaries of a `CmdAtom`: a stuffed translation ("x"
=> "dl") defers to the main loop. This "continuation" must be modeled in
`CmdAtom`, by checking global flags at undefined times, during undefined
circumstances.
Solution:
- After a stuffed "translation", eagerly execute the stuff buffer
(`exec_stuffed()`).
- Delete the CmdAtom "continuation" junk.
Note:
- op_colon runs its cmdline "nested", but that's fine because operators
already nest interactive sessions there (op_change runs edit()), and
the cmdline is frameless so the operator's frame can own/capture it.
