Fix typos + minor edits.

[AjayKMehta]

Thanks for creating such a wonderful module!

This PR addresses the following:

1. I noticed that there was a typo in README.md: New-Empahsis.
2. Also, fixed misspelling in function help.
3. I also believe this is a bug which I fixed.

Sorry for all the whitespace changes 😄

I think I have VS Code set to format documents on save and it trims whitespace at end of line.
