Closing terminal tab in a window group doesn’t send SIGHUP to the process

[Rinzwind]

When closing the tab for a Terminal window that has been put into a window group (use “Create window group” in the window’s window menu) (1.png), the process doesn’t seem to be sent SIGHUP as it doesn’t exit (2.png).

It looks like TerminalEmulator has no way to know whether a window is moved out of a tab group or a window is closed due to the associated tab closed, in both cases, GroupWindowMorph executes the method #removeWindow: without passing any event to TerminalEmulator to differentiate the two cases.

~~Furthermore, when a GroupWindowMorph is closed, there is no event passing down to the windows in the tab group.~~

I don't see a consistent way to handle these ~~three~~ cases...

It’s not clear to me either. I’ve reported some issues with window groups in Pharo 11: https://github.com/pharo-project/pharo/issues/12133 and https://github.com/pharo-project/pharo/issues/12134.
