No way to obtain update details via commandline

When using the "/quickcheck /justcheck /noerr" option, and the exit code indicates that an update is available, there is then no way to get at the text which describes the content of the update (the nifty text which tells you what has changed between your current rev and rev available).

It'd be really really nice if wyUpdate would build that same text and output it to a file (like "wyUpdateOutput.txt").

That way, the many many folks like me that are forced to use wyUpdate via the commandline could also display this text to the user.
