The current code does not comply to any generic MI parser as it violates the
MI grammar http://sourceware.org/gdb/current/onlinedocs/gdb_26.html#SEC264 ,
as pointed out by Dodji.

It may be compliant only to some hacky buggy parsers written specifically for
each MI command.

If we want to keep -break-list "script" to produce tuples we have to change it
from current
  script={"silent","return"}
to some
  script={line0="silent",line1="return"}
which will IMO also break any existing buggy parsers.

And GDB is now between major releases 6.8->6.9 which IMO means it does not
have to keep bug-to-bug compatibility.
