destsuffix and patchdir aren't quite the same though - destsuffix controls where 
the git repository is unpacked, whereas patchdir is the directory that the 
patch is applied in rather than where the patch file itself is written to.

(Oddly, as it happens, patchdir is in the documentation and destsuffix isn't - 
Scott, we'll have to take care of that.)
