OK, well maybe if someone types a CLI command, internally we make it do
the same thing -interpreter-exec console ... does? That would still make
me happy. Although I read below you said that's the case. Either it's
not the case, or it is and my GDB is old. I'll have to investigate.

Hmmm, that's not the case for me. Is this becase I'm using an older
version of GDB?

$ gdb --version
GNU gdb 6.3-debian

(gdb)
b main
&"b main\n"
^done
(gdb)
r
&"r\n"
^done,reason="breakpoint-hit",bkptno="1",thread-id="0",frame={addr="0x08048364",func="main",args=[{name="argc",value="1"},{name="argv",value="0xbf9d1464"}],file="main.c",line="4"}
(gdb)

(gdb)
-interpreter-exec console "b main"
~"Breakpoint 1 at 0x8048364: file main.c, line 4.\n"
^done
(gdb)
-interpreter-exec console "r"
~"Starting program: /home/bob/cvs/gdbmi/builddir/src/main \n"
~"\n"
~"Breakpoint 1, main (argc=1, argv=0xbfbcd7a4) at main.c:4\n"
~"4\t  argc = 1;\n"
^done
(gdb)

Because it's a totally useless feature that gives incorrect results.
Also, FE's might actually use it!
