NetworkManager/clients/tui/nmtui-edit.c
Beniamino Galvani b2fb80928e tui: return to initial menu after sub-forms exit 
When the user runs nmtui and selects an operation (edit, connect or
set-hostname) from the initial menu, the expectation is that once the
operation terminates the initial menu is shown again, so that the user
can perform multiple operations (like creating a connection and
activating it) without quitting.
