[Bug 1782570] [NEW] nohup is not preventing jobs from receiving SIGHUP when the shell ends

[Paulo Marcel Coelho Aragão]

Public bug reported:

nohup seems to have stopped working, not sure since when. It's easy to
reproduce:

1. Close your default browser
2. Run:

nohup sensible-browser &

3. Wait for the browser to open
4. Close the terminal emulator

The browser is terminated.

I have discovered that, instead of running nohup, the job has to be
removed from the job table:

sensible-browser &
disown
