* etc/NEWS: In terminal-oriented subshells, the EMACS environment
variable now defaults to Emacs's absolute file name, instead of to "t". * etc/PROBLEMS: Adjust tcsh advice for this. * make-dist (EMACS): Exit and fail if the EMACS environment variable is set to something other than an absolute file name. * lisp/comint.el (comint-exec-1): Set EMACS to the full name of Emacs, not to "t". * lisp/progmodes/compile.el (compilation-start): Likewise. * lisp/progmodes/idlwave.el (idlwave-rescan-asynchronously): Don't use expand-file-name on invocation-directory, since this might mishandle special characters in invocation-directory. * man/faq.texi (Escape sequences in shell output): EMACS is now set to Emacs's absolute file name, not to "t". (^M in the shell buffer): Likewise. * man/misc.texi (Interactive Shell): Likewise.
