Deprecating port list

I wouldn't expect any logic operations to actually take place in the  
examples above.  I'd expect it to do the command on each one  
independently.  When it comes across depends:expat (or something else  
that's a "reserved" name, I would expect it to function according to  
what the command is, and apply it to the following ports.

> port list depends:expat a*

For this, I would expect list to show me what ports starting with a  
depend on expat.  How it goes about it presently is different than i  
would expect.

> port info vim expat bzip2

I would expect port info to be run against vim, then expat, then bzip2.

It's just a matter of how I feel port list works.  I clearly  
misunderstood how it was going about its business.
