Something wrong with next in main git repository?

[Andy Parkins <andyparkins@gmail.com>]

Hello,

I've been keeping up with development only intermittently lately, and just got 
a warning from git fetch (in my git directory) that the update to my 'next' 
tracking branch was rejected as not being a fast forward.

I renamed my current up/next to up/oldnext and fetched the latest next, so I 
had up/oldnext and up/next to compare.  I'm probably concerned over nothing, 
but I can't find any mention of a rewind of next in the mailing list.

As far as I can tell a whole series of merges has just vanished.  For 
information:

 $ git rev-parse up/next up/oldnext
 0bdd7328c801101d752d0dfc9976a50651738897
 38fd5a1b23780381c3b6987c730f5ea3d8e1fc7f

 $ git merge-base up/next up/oldnext
 ef5b9d6e2286630bf8afb5bdf1c6e3356f3d50c7

Apart from all the merges that have vanished, some revisions have vanished too 
(vanished in the sense, they aren't on the branch any more).  i.e.

 $ git log --no-merges --pretty=oneline up/next..up/oldnext
 33369889 Revert "Support builtin aliases"
 3a569a00 Revert "parse_commit_buffer: don't parse invalid commits"
 1b1b2346 parse_commit_buffer: don't parse invalid commits
 f0a31f58 Avoid redundant declaration of missing_target()
  ... etc ...
 0edad442 adjust_shared_perm: chmod() only when needed.
 69a47520 Revert "pack-objects: use of version 3 delta is now optional."
 394737eb pack-objects: use of version 3 delta is now optional.

Have all these commits gone missing?  I'm certain that someone other than me 
would have noticed this sort of loss, so is it something I've done wrong or 
misunderstood?
