[PATCH] do not open editor in dumb terminal

[Amos Waterland <apw@us.ibm.com>]

Many people run git from a shell in emacs (obtained by M-x shell).  When
they try to do a commit without specifying a log message on the command
line with -m, git opens vi inside emacs, with unpleasant results.  I
think the right answer is to just refuse to open an editor in any dumb
terminal.
