   > Right, it would end up as `" "arg1", "arg2", "arg3" " actually. So i guess it is not that easy (without some string tokenization on runtime).
   
   tools/mkconfig.c tool supports destringifying things this.  It can convert " "arg1", "arg2", "arg3" " to automatically arg1", "arg2", "arg3".  See in cfgdefine.c:
   
        58 /* These are configuration variable name that are quoted by configuration
        59  * tool but which must be unquoted when used in C code.
        60  */

        68   "CONFIG_EXECFUNCS_NSYMBOLS_VAR",        /* Variable holding number of symbols in the table */

   It can also handle baskslash quoting of the internal strings:
   
       270           /* A special case is a quoted list of quoted strings.  In that case
       271            * we will need to remove the backspaces from the internally quoted
       272            * strings.  NOTE: this will not handle nested quoted quotes.
       273            */
