Accepting request 123669 from home:saschpe:branches:openSUSE:Tools

- Re-iterating the last change once again, 'git rev-parse --verify $REV'
  will return false even if $REV is a normal branch upon first clone
  of the repo. Thus 'git fetch $URL +$REV:$REV" is run initially. 
  However, the 'git checkout $REV' then fails because it's missing 
  tracking information. Therefore, try a normal checkout first and fetch
  the specific $REV only when that fails (due to reasons described below).
