Clarify aliases documentation

[laniakea64]

Resolves #1725 by documenting the scope of the alternative names defined with alias. Also updated the output of the example just b command to match what current just would do.

Added a comment, also, the branch is out of date. You might want to set the option that allows maintainers to edit pull requests, so I can do things like update the branch.

If that's enabled and you decide to make more significant changes than simply updating the branch, would the squash merge commit give you the co-author credit you'd deserve?

It would, since it adds a Co-authors: Casey Rodarmor <[email protected]> line to the commit message, but I usually just delete that, since it adds noise to the commit history, and I don't mind if I don't get credit. Plus I usually only make minor changes to PRs like that.

Nice, merged!
