Just thought it'd be nice to have quick access to them via tldr.

Definitely!

[CLAassistant]

All committers have signed the CLA.

Sorry for the commit spam, I wanted to commit your suggestions using the UI since it'd save me from having to co-author manually, but I wasn't sure how to accept multiple suggestions at once. ^-^'

@SethFalco the CLA isn't working because the email address that you used for the last commit ([email protected]) isn't added to your GitHub account. To fix this, you can either:

1. Change the email you used for the commit† to one of the emails attached to your GitHub account,

2. Or, preferably (and much easier), add the email you used for this commit ([email protected]) to your GitHub account.

†To change the email address of the last commit, run this command:

git commit --amend --author="Seth Falco <[email protected]>"

[SethFalco]

Sorry about that, was getting rid of old email addresses. ^-^'
I'll just add it back to my account and remove it again once this has been merged since multiple of the commits here used [email protected]; should've updated my local git config sooner.

You know, I don't think you should do that. It might cause weird CLA issues in the future with other PRs or something like that. Instead, run the command I mentioned, in option number 2.

I can do that if you'd like. If that may indeed cause problems though, then I think it'd be a flaw with the bot, since deleting email addresses is common enough that people may not even have access to addresses they may have used to commit in the past.

Thanks @SethFalco
