[master] Handle long commands in execute better

    Use token_print_indent_concat() to write the comamnd in an
    execute statement to the lease file.  This keeps the quotes
    with the command.  When using token_print_indent() and passing
    the quotes as a prefix and suffix they could be discarded
    if the command was overly long.
