I agree with that list as being a list of subdirectories of branches/ and 
tags/ that are not themselves branches or tags, but rather containers for 
branches and tags.

branches/st is more complicated than simply being a container for 
subdirectory branches.  It has a README file, five cli* subdirectories 
that look like branches of GCC, two subdirectories binutils/ and 
mono-based-binutils/ that are essentially separate projects (this is not 
of course any problem for git - having a branch sharing no ancestry with 
other branches is absolutely fine), and a subdirectory tags that contains 
tags of those various branches (I think).  So you want to say: 
branches/st/tags/* are tags; branches/st/* (subdirectories other than 
tags/) are branches; branches/st/README I don't know how you should handle 
(I suppose it could be a branch on its own, that just contains a README 
file, with commits affecting both README and other branches being split 
into separate commits to each piece; it is something that's still 
meaningful after the conversion and that ought to end up in the converted 
repository in some form).
