[tor-dev] only one signature on TBB 3.6.4

[Leif Ryge]

Looking at https://www.torproject.org/dist/torbrowser/3.6.4/ I see that there
is currently only one signature on sha256sums.txt for this release. As far as I
can remember, every other stable release in the 3.x series has had signatures
from at least 3 people.

Is this an aberation or should users not be expecting multiple signatures in
the future?

I was just advocating for torbrowser-launcher to require multiple signatures
when this happened:
