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.
