I really hate the default behavior of the space bar in notmuch-show; I don't want it to pop out of the thread that i'm currently view, and I especially don't want it to archive threads. The space bar should just be for viewing, not altering.
The following patch breaks out the food functionality from notmuch-show-advance-and-archive so that people can easily rebind it to the space bar. Although I do personally think we should change the default behavior, I leave the current behavior untouched, since I suppose there maybe are some people out there that like the current behavior and don't expect it to change. jamie.
