kconfig: begin PARAM state only when seeing a command keyword
Currently, any statement line starts with a keyword with TF_COMMAND flag. So, the following three lines are dead code. alloc_string(yytext, yyleng); zconflval.string = text; return T_WORD; If a T_WORD token is returned in this context, it will cause syntax error in the parser anyway. The next commit will support the assignment statement where a line starts with an arbitrary identifier. So, I want the lexer to switch to the PARAM state only when it sees a command keyword.
