emacsclient -t inside Emacs terminal

[Ulrich Mueller]

emacsclient.c contains a test for TERM being equal to "eterm" and
refuses to open a frame in this case. I wonder what is the purpose of
this? Calling "emacsclient -t" (to another Emacs) inside an Emacs
terminal seems to work quite well.

Besides, emacsclient doesn't test for "eterm-color" which is used as
terminal type in recent Emacs versions. So the test isn't even
effective.
