 The fundamental feature of 7.0 was that we get to break compatibility for
 the sake of correctness, so it makes no sense break correctness for the
 sake of compatibility with something which hasn't even been released.

 I was working on #2326 a little bit last week but I'm far from finishing.
 I have a first implementation of raise in run/write/read command functions
 and some changes make GUI start again. Nothing done on the rest of the
 code. Patch `run_with_raise_core.diff` attached.
