gdb "command" broken with -mi

[Ryan Johnson <ryan.johnson@cs.utoronto.ca>]

Hi all,

I noticed during a recent debug session that gdb's "command" command 
(setting actions to perform when a breakpoint triggers) doesn't work. 
You can start to enter the list of commands, but emacs ignores the "end" 
keyword that should terminate the list, forcing you to cancel the 
attempt with C-c C-c.

Is this a known issue?

Thanks,
Ryan
