} This seems to fix it
No, on second look, I mistyped my test case; it doesn't fix it after all.
Seems subst_parse_str() needs to turn Qtick into Tick as well as Qstring
into String. The following goes on top of 15871.
Now I'm concerned enough about this to wait for some feedback before I
commit it. All tests pass (including the new one below), but better safe
than sorry.
