Thanks for your PR for trying to fix this!

This code was added 3 years ago because I found that the GitHub web service is not stable enough.

At that time, the request to https://raw.githubusercontent.com/huan/gasl/master/src/gas-log-lib.js sometimes will fail, and it will succeed after retry one more time.

I believe GitHub service should be more stable today because the time has passed a lot and it gets more resources from Microsoft. So I'm ok with this PR to remove the duplicated code.

Please let me know what you think. If you think this code is ok to be removed after reading this, I'll merge this PR.

Hey huan!

I came across gast in this article here where they use only one call to eval. I have also been only using the single call and haven't run into any issues. I do think github should be stable enough now to remove the duplicate call.
