> No, at *column* 14.  Which I believe is the desired result, right?  Character 14 is the '(', the 'GRUB-config symbol itself starts at character 15.   But now I wonder whether we should be using a regex for that anyhow.  Do we expect the column number to change ever?

We don’t, but sometimes location info is not as precise as we’d like.

> I think it would be fine to fix the regex for Guile 2.0 only, but once the bug affecting 2.2 is fixed, it'll need to be applied there too.  Maybe it would make sense to fix both at the same time.

Yes, you’re right, it’s better to fix both.

Feel free to push.

Thank you!
