I installed Emacs.app with Homebrew, and used brew linkapps to create an alias in my /Applications directory.
Since I updated to OS X Mavericks yesterday, Spotlight and Alfred can no longer see this alias.
Since discovering the problem, I've tried reindexing my MacBook as described here, as well as reinstalling Emacs and restarting the machine.
Any other suggestions?

Found the answer here.
I needed to add the Homebrew cellar path to the list of paths under Features | Default Results | Search Scope, and then Alfred recursively scanned it and found Emacs.
On my Mac the path was
/usr/local/Cellar.And there was great rejoicing!
