`brew commands` outputs `alias` command twice.

That's what I get when running brew commands after latest updates.

Also, brew tap-info tells:

λ brew tap-info homebrew/aliases
homebrew/aliases: unpinned, 3 commands                     <------------ 3 commands?

I can’t reproduce on my work machine:

$ brew commands | cat
…
==> External commands
alias
all-versions
aspell-dictionaries
bin-conflicts
blame
bundle
...
truetest
unalias
...

$ brew tap-info homebrew/aliases
homebrew/aliases: unpinned, private, 2 commands

@bfontaine Quite strange. I noticed it after brew update, so I guess it somehow related to recent changes due to migration to use Homebrew::CLI::Parser.
Maybe there were leftovers after brew update, old cmd/brew-aliases.rb perharps?

Anyway, I untapped homebrew/aliases, then tapped it back and, luckily, everything went back to normal:

brew tap -d homebrew/aliases

I’m closing this until someone finds a way to reproduce the issue.
