[Qemu-devel] [PULL 38/38] qapi: Pass '-u' when doing non-silent diff

[Eric Blake <eblake@redhat.com>]

Ed-script diffs are awful compared to context diffs.  Fix another
'diff -q' while in the area (if the files are different, being
noisy makes it easier to diagnose why).

While at it, diff .err before .out, because if a test fails, .err
is more likely to contain the most important information for
fixing the failure.
