Matthew McClintock reported that older unannotated tags were not correctly being cloned and did not appear in info/refs. Further investigation revealed some dubious prefix comparison code for determining whether or not to write refs in info/refs. After comparing it with git's own http-backend.c, it appears upstream does not use this prefix logic. OTOH, I don't know what the reasoning was when the prefix logic was introduced. It appears to me to just be buggy, though it's possible there are other reasons, and we'll have to revisit this commit. But for now, Works For Me. Signed-off-by: Jason A.
