It's only used for the validation, SQLite handles the `--` just fine and the whole SQL textarea still gets sent once it passes validation.

I can add your test case to my branch later this evening though.

Really all we care about here is that if the FIRST lines of the statement begin with `--` we ignore them and only validate the statement starting from the first non-commented line.

Writing one is a bit of a challenge though!

The way you're stripping comments right now splits on newlines and removes any lines that start with `--`. I believe that will mangle the following example:

```sql
select '# Hello there

* This is a list
* of items
--
