Subject: [PATCH] brew.sh: auto-update 3rd-party taps more often.

When doing an `install`, `outdated` or `upgrade` and referring to a
formula or cask in a specific tap: you probably want to get the latest
version of that formula/cask more often than the default 1 or 24 hours.

Let's check for arguments for these commands that look appropriate and
auto-update every 5 minutes in that case.
