I keep seeing this warning every time I open an new shell on one of my machines:
Oh My Zsh brew plugin:
With the advent of their 1.0 release, Homebrew has decided to bundle
the zsh completion as part of the brew installation, so we no longer
ship it with the brew plugin; now it only has brew aliases.
If you find that brew completion no longer works, make sure you have
your Homebrew installation fully up to date.
You will only see this message once.
Message keeps coming back even though it threatens that "you will only see this message once."
Thoughts on how to 'fix' this? It appears to be triggered by
mkdir being aliased?!?
