One could easily write a small wrapper for elm which unsets any environ-
ment variables, then resets them aftwards.  Alternately write wrappers
for those programs that you want $PAGER to be set for.  In this way
you can probably control the settings and options more tightly, and the
default environment will be preserved even if the application does not
exit properly.

An example of the former under ksh:
elm () {
unset PAGER
/usr/bin/elm
PAGER='pg -n'
export PAGER
}

or alternately the latter under ksh:
alias rn='PAGER=pg EDITOR=vi rn -T -h -S1'

Probably easier that rewriting elm, and more generally applicable.
