I seem to also recall that Andrew also said that using CLI through MI was a
temporary arrangement (although I can't find that in the manual).

What's incompatible?  I mean in addition to, not instead of and here I'm
suggesting the opposite i.e that CLI support in MI is not deprecated.  My
feeling is that -interpreter-exec *does* provide a reliable interface into the
CLI while the hack that was used in GDB 6.3 didn't.  I'm just saying that we
may as well use it access CLI directly from MI.  First though I think we
should formally document the syntax of MI and CLI commands so that they don't
get confused.  CLI commands seem to always start with a lower case letter
while MI commands start with "-" (I see TUI uses "-" to mean scroll backward).
