Lately Homebrew learned to automagically clean up information about
outdated packages during other 'brew' commands, which might be useful
for the avarage user, but is a waste of time in CI build jobs, because
the next build jobs will start from the exact same image containing
the same outdated packages anyway.

Export HOMEBREW_NO_AUTO_UPDATE=1 to disable this auto cleanup feature,

The patch below adds HOMEBREW_NO_INSTALL_CLEANUP so maybe you meant
HOMEBREW_NO_INSTALL_CLEANUP here as well?

Thanks, good catch.  Apparently copy-pasted the wrong env var from the
patch to the commit message...

Applied an obvious rewording manually while queuing.

Thanks.

    ci: disable Homebrew's auto cleanup

    Export HOMEBREW_NO_INSTALL_CLEANUP=1 to disable this auto cleanup feature,
    shaving off about 20-30s from the time needed to install dependencies
    in our macOS build jobs on Travis CI.
