The current version of gnuemacs looks at the value of the environment
variable TERM to determine whether or not to run under X.  It was
pointed out to me that this is not the correct way to do it; this is
an artifact of an older implementation.

I'll fix this as soon as I have time to do so; it's a simple fix.

For those people who wish to take a look at it for themselves, the
code is in emacs.c in the function main().  The code around
getenv("TERM") is the part that needs to be changed.  There may be one
or two other places that also need to be fixed; fixing the code in
emacs.c should suffice for anyone who needs to fix it temporarily.
