          The variable MKSHELL contains the shell command line mk uses
          to run recipes. If the first word of the command ends in rc
          or rcsh, mk uses rc(1)'s quoting rules; otherwise it uses
          sh(1)'s. The MKSHELL variable is consulted when the mkfile
          is read, not when it is executed, so that different shells
          can be used within a single mkfile:

               MKSHELL=$PLAN9/bin/rc
               use-rc:V:
                    for(i in a b c) echo $i

               MKSHELL=sh
               use-sh:V:
                    for i in a b c; do echo $i; done
