[Unison-hackers] two questions

[Ben Willmore]

1. Is there a good reason why it should be impossible to diff a file
when the contents have been modified in one replica, and only the
properties in the other (Common.fileInfos)? Or is this a small bug?

2. On the Mac, can anyone tell me how to launch opendiff in the
background as my external diff command? I've tried many
differently-escaped/quoted variants of...
diff = opendiff CURRENT1 CURRENT2 &
... without success.  What really puzzles me is it returns immediately
when called from the command line.
