I'm confused:(  The policy is:

    - All shell commands in a rule are executed by separate shells  
(just like make).
      This means that the environment, directory, etc. do not persist  
across lines.
    - -Except- in a section.  This isn't actually an exception to the  
rule--the
      section is considered to be a single shell command.

If the "cd .." in the following is getting lost, it is a bug...

foo:
     section
         cd ..
         if $(equal $(CWD), $(d))
             eprintln(Ineffective cd)
             exit(1)
