Update: having done comparisons for every branch tip and tag, and investigated all the problems found and collectively fixed the bugs in question based on reduced testcases from that investigation, I believe all such problems causing comparison failures have now been fixed (and all problems causing tags or branches to be missing); I'm running a fresh conversion and comparisons to confirm. If those comparisons are clean I may also compare the refs/deleted tags and branches to provide additional points at which the tree contents are verified correct. Note: these comparisons are after deleting empty directories from the SVN checkout, because git doesn't represent empty directories. There are also two branches (c++-modules and melt-branch) where some files have SVN keyword expansion enabled, and the files with keyword expansion enabled need excluding manually from the comparison process. -- Joseph S.
