It seems like a trifle, but if the match frequency is high enough, the allocation+formatting of line numbers (and columns and byte offsets) starts to matter. We squash that part of the profile in this commit by doing our own decimal formatting. I speculate that we get a speed-up from this by avoiding the formatting machinery and also a possible allocation. An alternative would be to use the `itoa` crate, and it is indeed marginally faster in ad hoc benchmarks, but I'm satisfied enough with this solution.
