The "9 man intro" page has this paragraph containing the "exit" keyword.

'''
     DIAGNOSTICS
          In Plan 9, a program's exit status is an arbitrary text
          string, while on Unix it is an integer.  Section (1) of this
          manual describes commands as though they exit with string
          statuses.  In fact, exiting with an empty status corresponds
          to exiting with status 0, and exiting with any non-empty
          string corresponds to exiting with status 1.  See exits(3).

Starting 'emacs -Q' at the end of this typescript reproduces the problem.
