A bare Shell names the shell it goes back to, and 12:0 says columns count from 1

A bare Shell reset to the default without saying which; it now says
Shell: the default again, <shell> ($SHELL, else /bin/sh). A line:col of
column 0 said only address out of range; it now adds that a column
counts from 1.
