It is true with CLI commands in MI:

(gdb)
-interpreter-exec console "break fgfg"
&"Function \"fgfg\" not defined.\n"
~"Breakpoint 1 (fgfg) pending.\n"
^done
(gdb)

We don't appear to have any provision for such commands in MI and ISTR that Jim
Ingham has described difficulties with MI. In, particular they have
-break-commands to deal with the "commands" command. I was just proposing a
possible immediate fix, not to solve the general problem.
