Kevin, one more minor suggestion (and it's my fault for not noticing
and mentioning earlier):

Can you use a similar log entry format to the other developers? The
main difference is to group the symbol names in parens, this makes it
much easier to vgrep. With them all bunched up together, right next
to the file name, with no spaces and no parens, it's actually a lot
harder to browse the entry. Automatic parsing is actually less of a
concern, imho, although keeping to the standard format will of course
make that easier too.

Virtually anyone else's log entry can be used as an example, if you
need, as people have been pretty consistent in using this format.

Again, no biggie -- the change itself looks excellent, and the "###"
comments in propget-cmd.c were a good idea.

Thanks,
-K
