`AssertionError`: `assert _xterm_term_title_saved` in WSL (#14480)...

`AssertionError`: `assert _xterm_term_title_saved` in WSL (#14480) `AssertionError`: `assert _xterm_term_title_saved` In some (unknown) situation, it is possible that the `_xterm_term_title_saved` is unset, but the code would make a call to `_restore_term_title_xterm`, resulting in `AssertionError`. At least on replicatable reproduction is returning from `ipython` to `pudb` via `^D^D` on an empty cell. See more details in https://github.com/ipython/ipython/pull/14480 Signed-off-by: Stavros Ntentos <133706+stdedos@users.noreply.github.com> <details> <summary><em>was:</em></summary> In some (unknown) situation, it is possible that the `_xterm_term_title_saved` is unset, but the code would make a call to `_restore_term_title_xterm`, resulting in `AssertionError`. As title stacking does not seem to be getting traction (https://github.com/microsoft/terminal/issues/14575), do not set the `xterm` variants of `_set_term_title` / `_restore_term_title`. WSL detection: https://superuser.com/a/1749811/533196 Additionally, almost-`black` the file. </details>
