🚀 The feature, motivation and pitch

After the revert of 7cf9b94 we've identified a need to add a lint that checks file names to ensure that they're compatible with Windows machines.

Observed error: (from example commit)

Error: error: invalid path 'test/test_ops_gradients.py '

A simple check on changed files to ensure that the file paths do not include trailing whitespace should be sufficient enough for this.

A good place to start to add this would be here: https://github.com/pytorch/pytorch/blob/master/.github/workflows/lint.yml

Alternatives

No response

Additional context

This could potentially be expanded to include a litany of lints that check for compatibility on Windows. (see git-for-windows/git#2777 for more context)
