The disassembler output looks like:

(fhpd) disassemble 
[0.0]
Dump of assembler code for function: main
 0x804840d      <main+7>:       pushl   -0x4(%ecx)
[...]
 0x8048427      <main+21>:      mov     0x4(%ecx),%eax
*0x804842a      <main+24>:      mov     0x4(%eax),%eax
 0x804842d      <main+27>:      mov     %eax,(%esp)
[...]
 0x8048450      <main+4a>:      pop     %ebp
End of assembly dump

where as the list output looks like:

(fhpd) list
[0.0]
    43   print(char *what) {
    44     while (*what != '\0') {
    45       write(1, what, 1);
    46       what++;
    47     }
    48   }
    49   
    50   int
    51   main(int argc, char** argv) {
    52     // XXX: This forgets to check ARGC.
->  53     print(argv[1]);
    54     print("\n");
    55     return 0;
    56   }

we should be consistent with our pointers.

(The list output uses two spaces as the intent is to make use of the columns to
mark up additional information such as the presence of breakpoints, or the
presence of code (so a breakpoint can be inserted).
