Don't crash during repack of a reflog with pruned commits.
If the user has been using reflog for a long time (e.g. since its introduction) then it is very likely that an existing branch's reflog may still mention commits which have long since been pruned out of the repository. Rather than aborting with a very useless error message during git-repack, pack as many valid commits as we can get from the reflog and let the user know that the branch's reflog contains already pruned commits. A future 'git reflog expire' (or whatever it finally winds up being called) can then be performed to expunge those reflog entries. Signed-off-by: Shawn O.
