Incorrectly changing filenames for filepaths with directories ending in `b/` and `a/`

[kentcdodds]

Here's the diff I have:

The path in the input and output is different:

+ var/folders/kt/zd3bfncd0c3gjx25hbcq483c0000gn/T/kcdshop/diff/full-stack-testing/exercises__sep__07.remix-component__sep__01.solution.remix-stub/flq8snn26ke/app/routes/users+/$username.test.tsx

Notice the difference in the paths is the b/. I tracked this down to this line:

parse-git-diff/src/parse-git-diff.ts

Line 284 in f20636c

const added = parseMarker(context, '+++ ')?.replace('b/', '');

@kentcdodds Sorry for the inconvenience and Thanks for the reporting. There is currently no handling for the git diff with the --no-prefix option. I've created a PR to handle this. #21

[yeonjuan]

@kentcdodds It's fixed and released v0.0.12.
You can use the noPrefix option

parseGitDiff(OUTPUT, {
  noPrefix: true
});

[kentcdodds]

I believe this is now fixed! Thanks!
