docs: // trimCurrentPrefix removes a leading prefix of "./" or ".\" (referring to the
  // current directory in a platform independent manner).
  //
  // It is useful for callers such as "git lfs track" and "git lfs untrack", that
  // wish to compare filepaths and/or attributes patterns without cleaning across
  // multiple platforms.
