On my Kubuntu Feisty development machine with the stock emacs 
21.4a+1-2ubuntu1.1 package I get:

$ emacsclient --version
emacsclient 21.4
$ emacsclient --version 2>/dev/null
$ emacsclient --version 1>/dev/null
emacsclient 21.4

And I don't think it specific to Kubuntu because I remenber getting the same 
with emacs21 (before installing emacs22) on another (Debian testing) 
machine.

I didn't gave up, I am just waiting for the implementation of a scripted 
wrapper in git-mergetool.sh, that is now in 'pu', to mature. Then I will 
steal it so we have the same for git help.

Thanks.

I agree that it's better to do it for the users.

In fact just after this email, I will send a patch to "run_command.c" named:

"Redirect stderr to a pipe before redirecting stdout to stderr"

that will make my last patches to "help.c" work with both Emacs21 and 
Emacs22.

It would help if you could test with Emacs23 as I didn't installed it.

Thank you for testing my patches.

Christian.
