adisbladis ef3ed45c12 nix-gitignore: Optimise performance There are a few operations in this library that naively runs on every iteration while they could be cached. For a simple test repository with a small number of files and ~1000 gitignore patterns this brings memory usage down from ~233M to ~157M and wall time from 2.6s down to 0.78s. This should scale similarly with the number of files in a repository.	2020-12-07 14:14:20 +01:00
