As a followup this turned out to be the classic "PATH when doing GIT over
SSH" problem.

I have to say this is very unfun to debug, and even less fun to "fix"
even once you know this is the problem.  And what's more I know this is
the second time I've had to spend a night debugging this very problem.

I ended up having to make a ~/.ssh/environment file and then restart my
SSH server with "PermitUserEnvironment yes" added to sshd_config.

But I can't believe this is what I have to do just to pull from a machine
where I have GIT only installed in my home directory.  What if I were just
a normal user and couldn't change the SSHD config?  What hoops would I
need to jump through to get my PATH setup correctly? :)

It doesn't even work to put ~/bin into the PATH listed in the system wide
/etc/environment, because that does not do tilde expansion, SSHD just takes
it as-is.

Wouldn't it make sense to put the bindir into PATH when we try to do
execv_git_cmd()?  The code has already put the gitexecdir into the
PATH at this point.

Thanks!
