(MacPorts checks timestamps (or in trunk: checksums) of Portfiles only, not of patchfiles, to decide whether to autoclean.)

Hm, I was unaware of this problem until now. Should we calculate the
checksum over all the files in the port directory to remove the need for
such a pointless change?

At that point we don't know yet which patchfiles are actually referenced
in the Portfile. We can only assume that all files in the port directory
influence the build process somehow and any change to a file should lead
to dropping an unfinished build.
