While testing out, I noticed legitimate queries such as 
```
select * from books where title like 'Pragmatic%'
```
or
```
select * from books where title = 'The Pragmatic Programmer'
```
are blocked, due to the regular expression check here:
https://github.com/simonw/datasette/blob/main/datasette/utils/__init__.py#L185

Example as seen from a Datasette instance:
https://fivethirtyeight.datasettes.com/polls?sql=select+*+from+books+where+title+like+%27Pragmatic%25%27%0D%0A

I'd propose a regular expression like 
```
re.compile(f""pragma_(?!({'|'.join(allowed_pragmas)}))""),
```
instead of
```
re.compile(f""pragma(?!_({'|'.join(allowed_pragmas)}))""),
```

I can create a pull request with this change, unless the maintainers think it would allow unwanted queries to be executed.

I noticed as the number of rows increases the operation becomes quite slow, likely due to the creation of the `d = enchant.Dict(""en_US"")` object for each row.
