The 3.3 branch is way undertagged because of this unfortunately with
most tags only being available for bootstrap. I disabled the merging
for 3.3 for now. Once somebody retagged 3.3 (EasyHack maybe?) we can
still run the script over it (at least having the final releases easily
accessible would be good IMHO).
As for the other missing tags: I dont think we will miss the
tags <DEV300_m64 much, but for the ooo/OOO320 and ooo/OOO310 branches,
it seems we lost a few commits which were present in the old repos,
because:
- the branches do not exist on core
- the tags have vanished
- thus "git gc", which we run on the server, would mercilessly kill
  those commits, if I get that right
At least I cant find:
http://cgit.freedesktop.org/libreoffice/writer/commit/?id=3006a97452c49277166c348997387bcf1e77874bfind
in core. Not a big deal as those branches are rather old, but we should
keep that in mind, when we think about dumping the old repos for good.

Anyway, I updated the script a bit.

Best,

Bjoern
