Subject: 24.5; cannot end gdb breakpoint command list
Date: Wed, 29 Aug 2018 10:37:16 -0400

When running gdb in emacs I cannot terminate a breakpoint command list.  
It says to terminate the command list by typing "end" by itself on a 
line, but when I do it continues to prompt for additional commands.  I 
can get out of this mode using ctrl-C, but the breakpoint commands are 
not saved.

Example:

(gdb) i b
Num     Type           Disp Enb Address            What
3       breakpoint     keep y   0x000000000043893b in 
add_rrmsg_to_vector(msg_t const*) at springsolver.cc:2496
    breakpoint already hit 5 times
(gdb) command 3
Type commands for breakpoint(s) 3, one per line.
End with a line saying just "end".
