- Fix and attempt to simplify :Frame/:Up/:Down documentation.
- Accept a count instead for :Up/:Down/+/-.
- Update the "Last Change" dates.
- Fix a missing :let (caused an error if gdb fails to start).
- Wipe the prompt buffer when ending prompt mode (if it exists and wasn't wiped
by the user first). Avoids issues with stale prompt buffers (such as E95 when
starting a new prompt mode session).
- Kill the gdb job if the prompt buffer is unloaded (similar to what's done for
a terminal buffer). Fixes not being able to start a new termdebug session if
the buffer was wiped by the user, for example.
