This bit me too, and making things worse, the truncate killed the git 
history that presumably had the answer I needed to fix it up. 
=:^(  Fortunately I had a bit of a clue due to preemptively following the 
portage changelog where I had seen a hint, so I was able to dig it up 
again without the git log help that's definitely now my first instinct.

Long story short and for the record, manual intervention indeed and I wish 
it had at least come with a news item, but here's the magic that fixed it 
for me.

I had one of these previously, IIRC clone depth, but both are now needed.  
I put these in the [DEFAULT] section here because I run several overlays 
and I "want" access to proper git logs and history by default. (FWIW 
"want" is the polite, cooled down, version; the situation was considerably 
more sweary when I lost that history and instinctively I tried to look in 
the git history for why, but of course it was GONE!)

repos.conf, [DEFAULT] (or [gentoo]) section:

clone-depth     = 0
sync-depth      = 0
