I think he is saying that the MI output of gdb, in this case, does not
conform to the MI grammar as given in the manual.  So, if an
implementer tries to write an MI parser relying strictly on the
grammar, it will not work in this case.  From one point of view this
means having a hacky parser...

Yuck.  I guess options for fixing this are pretty limited.

How about documenting, in the "GDB/MI Output Syntax" node, that
sometimes lists are formatted like tuples?  That may, at least,
prevent future MI implementers from having to rediscover this problem
on their own.
