Phew!

This only leaves ``x/...''.  How does that behavour compare?  The most 
important thing was that given:

(gdb) print main
$1 = {int ()} 0x101405c <main>
(gdb) print/x &main

things like:

(gdb) x/i main
disassembled <main>
(gdb) x/i 0x101405c
disassembled <main>
(gdb) x/b 0x101405c
hex dump of main

and

(gdb) disassemble main
disassembled <main>
(gdb) disassemble 0x101405c

continued to work (assuming that they did before :-/).  Similar for data 
values.
