I don't have or use tmux, but I'm going to guess that `kill-window' sends
a SIGHUP to the process group and follows it up with a SIGKILL. The
`source' turns off saving to history -- the `source' gets saved in the
history list, not the commands it runs -- and is still running when the
SIGHUP arrives. The SIGHUP causes the shell to exit without saving the
history because history is turned off when the signal handler runs.
