Well, whatever, I relaunched PM again and the weirdness appears to have vanished. I'm back to having a regular Quit at the bottom of the dock menu.
Perhaps not unconnected, the reason that I relaunched PM was because I minimised the Recent Mail window to the dock, and it didn't want to come out again. Pressing Cmd-Ctrl-R called a second instance of the RM window (leaving the original one wedged in the dock), and at that point I thought that things had gotten wiggy enough and just restarted Powermail. Perhaps the Force Quit thing was due to a window management error waiting to happen? Anyway, it's all sweet now.
