    PR3217: Fix systemtap.base/vars.exp
    
    This test has a grep on pass-3 code, which started matching too much
    with the new compiled-printf output.  This tightens that grep down a
    bit, and adds a comment explaining what the test is trying to do.

    PR13272: Fix quoted strings in the printf shortcut path
    
    For printf strings with no arguments, we usually skip all the printf
    path altogether and just use _stp_print.  However, the compiled-printf
    changes affected the level of string escaping, which broke for a case
    like printf("\"quote\\this\"\n").  We must make sure that this shortcut
    path uses an output-quoted string literal.
    
    * translate.cxx (c_unparser::visit_print_format): Generate an output-
      quoted format_string too, for use by the _stp_print shortcut.
      (preprocess_print_format): The "%s\n" case shouldn't alter components.
    * testsuite/buildok/printf.stp: Add "%s" and "%s\n" shortcut tests too.
