------------------------+--------------------
 The rsync port used to use an official patch to add support for HFS
 compression. As far as I know, "HFS compression" continues to be supported
 on APFS and is a valuable feature that we want to enable if we can.

 This patch was removed when the port was
 [changeset:3b08efaebe3b7413093b981f2f4ad661d27cffac/macports-ports updated
 to 3.1.3] with the remark:

 > hfs-compression.diff is marked by upstream as broken as of 3.1.3

 Homebrew seems to have followed our lead in removing this patch, but
 nobody seems to know why we did this. The rsync mailing list has been
 [https://lists.samba.org/archive/rsync/2018-August/031704.html twice]
 [https://lists.samba.org/archive/rsync/2019-March/031884.html asked] and
 nobody has replied. John, could you clarify where upstream says this patch
 is broken, or explain in what way it is broken?

 In addition, we have the problem that when HFS compression support was
 added to the rsync port, we added not only hfs-compression.diff from the
 official patches directory but also hfs-compression-options.diff. Where
 did that second patch come from? Jim, did you make it?
