Hello,
I found a typo in a comment in parse.y, line 1175:
```
likeop(A) ::= NOT LIKE_KW|MATCH(X). {A=X; A.n|=0x80000000; /*A-overwrite-X*/}
```
`/*A-overwrite-X*/` would be a typo of `/*A-overwrites-X*/`, and it would not work as a special comment.
I'm not sure how much this typo will affect the functionality, but just wanted to report it.
Thanks,
Ryusei
