T9579 fails on OS X

As pointed out in ticket:9579#comment:101040 the testcase T9579 fails on OS X,

Actual stdout output differs from expected:

The issue appears to be a difference in sed's behavior on OS X. The number in the error message is supposed to be replaced by NUM with sed -e 's/[0-9]* bytes/NUM bytes/g'. Perhaps someone with access to an OS X box could shed some light on this?

mentioned in issue #9579 (closed)

changed milestone to %8.0.1

changed weight to 5

added Tbug Trac import labels

Maybe a similar change as in 82cf6724 can be performed, where \+ was replaced by \{1,\}.

Oddly enough I can't reproduce this on our OS X test box.
