did you check that to_output_relative_path works as we expect?

[dzbarsky]

hmm can you check with -s what gets sent here? I'm not convinced this .path won't break it

[jbedard]

I think this will be an issue basically anywhere a js_binary is run?

Does that mean this PR has essentially no effect?

[dzbarsky]

yes, i believe so

[jbedard]

did you check that to_output_relative_path works as we expect?

It only uses short_path so I think we're good?
