[ldapvi] [PATCH] Handle editor commands with arguments

[Anders Kaseorg]

Previously when the EDITOR environment variable is set to a command
with arguments, such as ‘emacsclient --alternate-editor emacs’, ldapvi
would fail to launch the editor:

$ ldapvi
     26 entries read
error (misc.c line 180): No such file or directory
editor died
error (ldapvi.c line 83): No such file or directory

Fix this by launching the editor via /bin/sh.
