    You are right: ; is not necessary.
    NOPIPE=yes rancid -d -t type devicename
    is is a perfectly valid syntax according to POSIX Shell Grammar Rules.
    It works with bash, dash, ksh, zsh and other shells.
    see "simple_command" syntax and rule 7, which defines "ASSIGNMENT_WORD".
    simple_command   : cmd_prefix cmd_word cmd_suffix
                     | cmd_prefix cmd_word
                     | cmd_prefix
                     | cmd_name cmd_suffix
                     | cmd_name
    cmd_prefix       :            io_redirect
                     | cmd_prefix io_redirect
                     |            ASSIGNMENT_WORD
                     | cmd_prefix ASSIGNMENT_WORD
    You don't need the ; and you dont need export, and you can even put
    redirects, as long as assignments are before the command.
    Example :
    XYZ=foo </tmp/x >/tmp/y A=1 B=bar mycommand myarg
