The patch seems to forget to handle the tab-completion for

Thank you for your patch.
I have two comments.

1. When I executed git apply, an error occured.

$ git apply ~/Downloads/fix-tab-complete2.patch

COMPLETE_WITH_SCHEMA_QUERY(Query_for_list_of_tables, " UNION SELECT

warning: 1 line adds whitespace errors.

2. The command "LOCK TABLE a, b;" can be executed, but tab-completion
doesn't work properly. Is it OK?

It's OK for now.
But it should be able to handle a case of multiple tables in the future.

+             Matches("LOCK", "ONLY", MatchAny, "IN", "ACCESS|ROW") ||
+             Matches("LOCK", "TABLE", "ONLY", MatchAny, "IN", "ACCESS|ROW"))

I think this code is redundant, so I change following.
---
    else if (HeadMatches("LOCK") && TailMatches("IN", "ACCESS|ROW"))
---
I created the patch, and attached it. Do you think?

Thank you for update!
I think that your code is more concise than mine.
There seems to be no problem.

The patch looks good to me, too. I applied cosmetic changes to it.
Attached is the updated version of the patch. Barring any objection,
I will commit it.
