Re: minimalistic MI catch support

[Nick Roberts <nickrob at snap dot net dot nz>]

A few further remark about catchpoints:

(gdb) catch catch
Catchpoint 2 (catch)
(gdb) catch throw
Catchpoint 3 (throw)
(gdb) catch fork
Catchpoint 4 (fork)
(gdb) catch exec
Catchpoint 5 (exec)
(gdb) info break
Num Type           Disp Enb Address    What
2   breakpoint     keep y   0x07dae1aa exception catch
3   breakpoint     keep y   0x07daf001 exception throw
4   catch fork     keep y
5   catch exec     keep y

The first two are of type breakpoint and their nature is given under the
heading "What".

The second two have their own type: "catch fork" and "catch exec" (I must
admit that I don't understand how this gives differerent behaviour from using
"break fork" and "break exec").  Also for some reason, they have no address.

This inconsistent description probably doesn't matter for CLI, but it is
also used for MI output, for which it does seem inappropriate.

Would it be a good idea to change it to:

Num Type           Disp Enb Address    What
2   breakpoint     keep y   0x07dae1aa exception catch
3   breakpoint     keep y   0x07daf001 exception throw
4   breakpoint     keep y              fork
5   breakpoint     keep y              exec

or something like:

Num Type             Disp Enb Address    What
2   exception catch  keep y   0x07dae1aa 
3   exception throw  keep y   0x07daf001 
4   catch fork       keep y
5   catch exec       keep y

to make it easier to parse the MI output.
