In case a fix was not propagated yet to upstream, the
original commit sha won't be found hence the fix of this
fix will be missed during the cherry-pick.

Since dim cherry-picks reliably adds the -x "(cherry picked
from" message, let's also grep in the log to see if that
was the case, before we give up and forget.

Also, if that's the case, let's then add the extra 'Fixes:'
tag for a better record.
