GitHub's web-based editor is great for making a quick change to a file. But how can I set the email address used in my commit? I have several email addresses associated with my account. It seems to use what GitHub thinks is the primary email address (the one GitHub uses to send me email), but I can't figure out how to change that either.
(Note: I know how to change my email address in a local repository using
git config. I'm only asking about GitHub's online editor.)
