We currently filter out `TMUX`, but this breaks displaying some caveats.
This also enables an alias I use (and improved by @Rylan12):
brew alias fzp='!id="$(gh pr list -L200 -R github.com/Homebrew/homebrew-core | TMUX=$HOMEBREW_TMUX fzf-tmux -p "90%,50%" --multi | cut -f1)"; [ -n "$id" ] && brew pr-publish --autosquash $id'
- For some of these I changed `context` to `describe` as it fit better
rather than contriving a "when", "with" or "without", or massively
restructuring the tests.
- Only display the completions caveats from the current shell (assuming
it's one of Bash, ZSH or Fish)
- If the completions location isn't in the ZSH `FPATH` then link to the
documentation explaining how to do so.
Fixes https://github.com/Homebrew/brew/issues/8984
These instructions are currently incorrect and need to be ported to
`python` 3.x and `python@2` formulae. Until then it's better to not have
them than have them be incorrect.
Closes#3890.
