How about a variable `process-terminal-type' (default: "dumb") that is
automatically subbed into `process-environment' when starting a
subprocess?  This would be best done in `child_setup' (callproc.c) like
PWD is now, but it could even be done in Lisp.  Several packages already
do tricks like this (`man.el' let-binds `process-environment' to do
exactly this; `comint.el' let-binds it to a constructed sequence with new
TERM settings), so it shouldn't cause any problems.  However, that would
necessitate a(nother) wrapper layer for `start-process', `call-process',
and `call-process-region'.

On the subject of PWD in callproc.c, why are some environment references 
done with egetenv() and others with plain getenv()?  There are no comments 
describing the inconsistency, and while I can understand wanting the 
"original" value of a variable (particularly in uses where Lisp is not 
aware that the environment is being consulted, so there are no issues of 
surprise), there is not even consistency among the uses of single 
variables (like TMPDIR).
