pg_upgrade diffs on WIndows

I realized this morning that I might have been a bit cavalier in using
dos2unix to smooth away differences in the dumpfiles produced by
pg_upgrade. Attached is a dump of the diff if this isn't done, with
Carriage Returns printed as '*' to make them visible. As can be seen, in
function bodies dump2 has the Carriage Returns doubled. I have not had
time to delve into how this comes about, and I need to attend to some
income-producing activity for a bit, but I'd like to get it cleaned up
ASAP. We are under the hammer for 9.2, so any help other people can give
on this would be appreciated.

cheers
