I've started to move the !hack command as Hack into the core.
Currently doesnt works for the debugger, but i'll finish the
change soon.
Btw thanks to pof to warn me about the missing libexec scripts
in Makefile:install.. This make me review the dwarf-lines script
to make it work again for the new comment infrastructure.
$ cat a.c
main()
{
printf("Fuckmenot!\n");
}
$ gcc -g a.c
$ radare dbg://./a.out
(...)

Yeah, thats quite cool for analyzing compilers with dwarf support :)
Remember that you can move the comments to the right using the asm.cmtmargin
and limit the number of comments per offset with asm.cmtlimit.
Have fun! ;D
