I tried to run brew update and I get an error about my local changes would be lost if I merged. I tried committing my local changes (don't remember making any, but it's been awhile), and that made things worse. Here's the output: MBP:Library User$ sudo brew update error: The following untracked working tree files would be overwritten by merge: Library/Aliases/fastcgi Library/Aliases/htop Library/A
