Hm, there are no new local branches here; I fetch to the same branches
as the other remote:

git fetch -q anon-origin master:master REL9_2_STABLE:REL9_2_STABLE REL9_1_S=
TABLE:REL9_1_STABLE REL9_0_STABLE:REL9_0_STABLE REL8_4_STABLE:REL8_4_STABLE=
 REL8_3_STABLE:REL8_3_STABLE

Note this fails (which is what I want) when it's not a FF pull.  So my
local repository hasn't had any corruption.  In fact, to observe the
breakage, I had to do a "git fetch anon-origin master:anon-master".

I guess there clearly weren't enough protections in the gitmaster server
to prevent me from causing major breakage (hopefully there are now), but
then I'm so chicken that I triple-check these things before pushing, so
no major harm has been done by me to date, even though my setup may be
theoretically dangerous.
