Whether they have history in common is, in the case of 
libstdcxx_so_7-2-branch, a subjective question (that branch was created in 
SVN by creating the directory for the branch, then copying just the 
libstdc++-v3 subdirectory, so that subdirectory does have history in 
common with trunk).  In fact I've seen it go, in the reposurgeon 
conversion, from being an orphan branch to a non-orphan and back again, as 
details of the exact handling of empty commits (a commit that only created 
the directory for the branch, in this case) changed (and I've wondered 
about making the reposurgeon conversion explicitly reparent the commit 
that copies the libstdc++-v3 subdirectory, on the basis that being 
connected to the main history of trunk is more useful than not being so
