   7# The whole contents of this file is run by dot-sourcing it from
   8# inside a shell function.  It used to be that "return"s we see
   9# below were not inside any function, and expected to return
  10# to the function that dot-sourced us.
  11#
  12# However, older (9.x) versions of FreeBSD /bin/sh misbehave on such a
  13# construct and continue to run the statements that follow such a "return".
  14# As a work-around, we introduce an extra layer of a function
  15# here, and immediately call it after defining it.
