## Message

```
Prevent out of bounds access in `recursive_score_match` (#35630)

Closes https://github.com/zed-industries/zed/issues/33668

The recursive case increments both indices by 1, but only one of the two
had a base case check in the function prologue so the other could spill
over into a different matrix row or out of bounds entirely.

Lacking a test as I haven't figured out a test case yet.

Release Notes:

- Fixed out of bounds panic in fuzzy matching
```
