This is still an issue in 12.04. The bug is important if you want to
have multiple versions of emacs available, and you want to use daemon
mode.

Suppose you have both emacs23 and emacs-snapshot installed, and
/etc/alternatives/emacs points to /usr/bin/emacs23. In this case, any of
the following commands will start an Emacs daemon using emacs23:

1. emacsclient -a "" -c
2. emacsclient.emacs23 -a "" -c
3. emacsclient.emacs-snapshot -a "" -c

Arguably, command number 3 should use emacs-snapshot to start the
daemon. But instead all of them start /usr/bin/emacs, which points to
/etc/alternatives/emacs, which points to /usr/bin/emacs23. To fix this,
each version of emacs would have to be patched to use its own version-
specific executable to start the daemon. This would ensure that the
correct emacs version is always used to start the daemon.
