Yes, there could even be some benefits. In general, it is better to
flush if one knows that the following output won't be sent before
some time.

Yes, and IMHO, since diff often generates more output, the problem
is less important with diff.

Also, stdout and stderr should be synchronized. This is currently not
the case due to the lack of flush. For instance, I currently get:

dixsept:~/wd> svn info -r10000 tex www | grep '^URL'

instead of
