dispatch: fix silly blackbox entries when hg is interrupted

When hg is interrupted, it creates ui.log like this:

1970/01/01 00:00:00 user @0000000000000000000000000000000000000000 (62488)> killed!
 exited 255 after 1.78 seconds

This is due to a scoping problem: two different uses of the name "msg"
collide. So rename one of them.
