> The "g" stands for "git" and it's not part of the SHA1: 4ca117 are the first six digits of the SHA1 at the HEAD of the branch
Ah, now that you spell it out, it's obvious. I swear I kept staring at the git hash to find the "117" in "g4ca117" in http://orgmode.org/cgit.cgi/org-mode.git/commit/?id=4ca1179c9e9c707267ac3738cc7c8442001b204b but I never saw it! Now it stands out clear. And of course, I should have realized that "g" can never be part of the hex hash. Thanks, and also thanks for confirming that you see this error too.
