"M-x shell" is not a shell, it is an Emacs interface to a shell.

This is not a bug. I'm okay with adding a new optional feature that would disable the above behavior, but it must be off by default.

It looks like this should be fixed in `shell-cd` (which should also fix `shell-process-pushd`) by implementing "custom" path handling (compared to Emacs default path handling behavior).
