After some experimenting it seems to me that there is another bug, at
least in my case

,---------------------------
| (call 'emacsclient
|    "-e"
|    "(message \"CALL 1\")")
`---------------------------

does not work, while 

,---------------------------
| (call 'emacsclient
|    "--eval"
|    "(message \"CALL 1\")")
`---------------------------

does (on Archlinux). 


I have another problem not yet solved - I want to call an Emacsclient
with a file to open and some code to evaluate. Using the "-c" and
"--eval" options in one call gives an error for me, and this seems to be
in accordance with the manual that says its either the one or the other. 

However, if I try two sequential calls instead, it works somehow, but
not as intended. These two calls directly after another

,--------------------------
| (call 'emacsclient
|    "-c" "my/dir/my-file")
`--------------------------

,---------------------------
| (call 'emacsclient
|    "--eval"
|    "(message \"CALL 1\")")
`---------------------------

open a new emacs-frame showing a 'my-file' buffer, but in the *Messages*
buffer there is no CALL 1 message. But when I kill the Emacsclient-frame
with C-x C-c, CALL 1 is shown as return value in the calling external
program and now appears in the *Messages* buffer too. It seems the
second call is waiting for the first call to terminate.

Now I wonder how I can call Emacsclient with a file I want to edit, but
make it (immediately) evaluate some code when it starts up? Is that
possible in the call(s) itself, or do I have to use hooks or something
like that?
