This reverts commit b7aaad60308856611349079288bdb274668e4a16.

When deps command is passed this option, it will only show the dependencies
for the installed forumas. This option overrides the '--all' option.

Relying on the output of `tapped` results in ignoring formulae which
already exist in core, with messages like "Tapped 0 formula" for
non-empty taps.

Closes Homebrew/homebrew#18169.

`brew untap` without arguments currently errors out (as it should), but the
error message is generic and unhelpful. (The error message is borrowed from
a method in the tap command - `tap_args`.)

The previous fix only looked at the current Homebrew but we should
discard hits from other installations of Homebrew too.

This reverts commit 6963a356510256762e425b5dbe2ee8c9ee0ace68.

When given no arguments, this should return the stable version, but it
hasn't since we stopped setting this direction in the class's @version
variable.

The form "attr :name, true" is deprecated and causes Ruby to emit a
warning in verbose mode. Using attr_{reader,writer,accessor} is more
clear anyway, so do so.
