why only the QString variants? *all* readEntry variants should
understand [$e] - and this is also the kde3 behavior (except for the
*Untranslated variants, but this is most probably not intentional).

there is some confusion with [$e] vs. list handling.
- kde3 expands before splitting. this may lead to spurious splits.
- your code expands after splitting. this makes scripting lists
  impossible. also, shell statements containing the separator char will
  be torn apart, which is highly unexpected.

i think the proper solution is expanding first and introducing an
additional escape to separator-quote the expanded string:

$ export VAR="foo;bar"
$ cat foorc
# note that this contains additional low-level quoting
# "foo" "bar"
ListKey1[$e]=$VAR
# "foo" "bar"
ListKey2[$e]=$(echo "foo;bar")
# "foo;bar"
ListKey3[$e]=$\\VAR
# "foo;bar"
ListKey4[$e]=$\\(echo "foo;bar")
