bug#18517: 24.3.93; `--eval' option to "emacsclient -a ALTEDITOR" should be should ignored if it falls back to alternate editor

[Jordan Wilson]

Hello,
calling the command "emacsclient -a nano --eval '(message
"Hello world")'", if the emacs server is not started, nano (or any other
editor, including "-a emacs") will open a buffer with the name of
"(message "Hello world")". This is not in accordance with the man page
for "emacsclient":
   -e, --eval
   do not visit files but instead evaluate the arguments as Emacs Lisp
   expressions.

That suggests in the case of falling back to the alternate editor, the
argument following the `--eval' option be ignored. If not, the
documentation needs changing to clarify this.

I've produced this bug on both 24.3.93.1 and the trunk as of yesterday.

To reproduce:
1. Kill emacs or `server-force-delete'
2. emacsclient -a *alternate-editor* --eval '(message "Hello world")'.

Thanks,
Jordan.
