@JonasBa If I'm reading this right, this just makes it so that one file referenced in --env-file-if-exists would be watched only if there is no file provided with --env-file. But the bug we still have is that you wouldn't be able to specify both an --env-file and an --env-file-if-exists argument and have both be watched.

const kWatchedPaths = ArrayPrototypeMap(getOptionValue('--watch-path'), (path) => resolve(path));
const kPreserveOutput = getOptionValue('--watch-preserve-output');
const kCommand = ArrayPrototypeSlice(process.argv, 1);
