- parser.c: Fix prompting in old style backquote expansion. Fixes PR/2139
and many user complaints why the shell hangs in echo "`"
- eval.c: Fix exitstatus invalid resetting in `if' statements were:
if (exit 3); then
echo foo $?
else
echo bar $?
fi
printed 'bar 0' instead of bar 3
Return zero status if `else' clause is empty.
