Ok, that explains it.  update-server-info wasn't a built-in, so didn't
have to look at its name to decide what to do.  It didn't have to spawn
other git commands from GIT_EXEC_PATH so running the command directly
without setting the environment variable happened to work.

But such a usage (this doesn't have anything to do with the symlinking)
was deprecated way before 1.5.4 [*1*], so the answer is still "don't do
that" ;-)

Thanks for a clarification.
