Research direction
Reproduce the crash by running micro * with the listed mix of directories and files, then selecting the second tab. Start in cmd/micro/cellview.go:171 and follow the calls through view.go and micro.go. Done means the tab can be selected without an index-out-of-range panic and the shell does not receive the garbage @:!#:!.
