github note - ignore whitespace (now with UI bit)

Around 5 years ago I posted this tidbit. and it came up again today:

When doing a Pull Request via github you can add a ?w=1 to the end of a url e.g.  https://YOURCOMPANYSITE/BRANCH/pull/1785/files?w=1

I reposted after sharing it with a coworker who didn't realize it existed, and a different coworker mentioned there's a UI for it: (that forces a reload because it's just a wrapper for the URL)

anyway, this obviously makes it easier to confirm code like where you're making a split or other conditional test permanent, and the only difference is of a big code block is indentation from when it was a conditional...
