Sounds nice.

We already have the 'echo' action which is much faster than 'list'.
We're also trying to avoid adding any more actions that would be
equivalent to 'echo <pseudoport>'.

The 'rdeps' action introduced in 1.9 does this.

The 'leaves' pseudoport does basically the same thing, though it also
excludes ports with the requested bit set.

Actionflags are of the form --foo, so this should be something like --size.

There are several logically distinct features being added here, so it
would make it easier to review if there was a separate patch for each
one. An 'svn diff' against trunk/base/src/port/port.tcl would be best.

Open an enhancement ticket in Trac for each one so they aren't forgotten
about.
