 I propose to add an action named "space" to show the disk space used by
 installed files in an active port. Similar information is available by
 running the command "`du -sk /opt/local/var/macports/software/<port
 name>`", but an action is a little handier. The total doesn't include any
 files used to create or keep track of the port, such as those in
 /opt/local/var/macports/{receipts,sources}.

 The patch adds support for this action, as well as options that specify
 the default units for sizes: -K for KiB, -M for MiB, -B for bytes. These
 options are applicable to other (such as another proposed feature of mine
 to include file sizes when listing port contents), which is why they are
 global options rather than action flags. Another possible option (-H)
 would say to make the sizes human readable (i.e. autoscaled), picking the
 unit that best matches the value magnitude. As this should be the default
 behavior, I've left out this option for now.

 Example usage:
 {{{
 $ port space autoconf gawk zip
 2.960 MiB autoconf
 5.038 MiB gawk
 800.381 KiB zip
 8.779 MiB total
 }}}
