There are now four more repositories available.

git+ssh://gcc.gnu.org/home/gccadmin/gcc-reposurgeon-2a.git
git+ssh://gcc.gnu.org/home/gccadmin/gcc-reposurgeon-2b.git
git+ssh://gcc.gnu.org/home/gccadmin/gcc-reposurgeon-3a.git
git+ssh://gcc.gnu.org/home/gccadmin/gcc-reposurgeon-3b.git

The 2a and 2b repositories are similar to 1a and 1b, but have fixes to 
issues 4 and 5 I listed (they include attribution extraction from 
ChangeLog.<branch> files and all of Richard's commit message 
improvements).  The 3a and 3b repositories have further improvements to 
the conversion machinery.  Verification shows that 3a and 3b have execute 
permissions on files exactly the same as in SVN, at all (non-deleted) 
branch tips and tags.  .cvsignore files are present as requested.  There 
are mergeinfo improvements to avoid spuriously marking cherry-picks as 
merge commits and to avoid having excessive numbers of merge parents in 
some cases, but the mergeinfo improvements should be considered a work in 
progress; further improvements have since been implemented in reposurgeon 
since then to allow many more merges to result in git merge commits 
without false positives for cherry-picks, so will be in the next trial 
conversion after these ones.
