It will need a change to the versioning files if its done after versioning
is enabled

iam not happy about suboptimal solutions.
but if all of the following are true than iam ok with it
1. We have no volunteer to implement a more optimal solution
2. We do have a volunteer to implement a solution based on unchanged ELBG
3. The final code is at least as good as some common tool like gimp in terms
   of subjective quality
4. Off course the patch must be clean&simple&... like any other patch

Its not that you shouldnt use gotos but rather that you should write
readable code and code with gotos often but not always is less readable
