Just an idea about extending this idea: What if the shell
field for that user does not contain a shell, but the name
of the editor instead? I assume it has to be "noted" in
/etc/shells to work, but a passwd entry like
could work (haven't tested that). A list of the files can
be obtained when opening a file ^KE and pressing the Tab key.
It would be worth testing if shell escapes like !command
will work in this constellation...
