Few days ago I noticed that some tags, e.g. R2_5_4 or R2_5_5 are not
only on B2_5_Release branch but do actually have much less common
history with it than I would expect (e.g. "git log B2_5_Release..R2_5_5"
gives me 9260 commits). This is probably an artefact of the import from
SVN but it might mean we effectively keep multiple copies of some parts
of the branch.
BtW., "git gc --aggressive" reduced the size of my local repository from
462 MB to 155 MB.
