-------------------------+--------------------------------
 I thought I'd already submitted this proposal, but cannot seem to find it:

 The state file can be used to record which patches have been applied
 successfully, and this information can be used to skip those patches. I
 find this a useful feature (inspired by the Debian build scripts) when
 applying an upstream update to a port that has a large source footprint
 and/or a large number of patches. With this mod, one can simply invoke
 `port patch` (or any subsequent build command) repeatedly until all
 patches apply cleanly.
 In its current form, one still has to revert the failed patches by hand.
 It should be possible to avoid this by testing each patch before applying
 it (using patch's `--dry-run` option) but I'm not sure how one would best
 implement that (a temporary addition to `patch.pre_args`?).
