How to print a null-terminated string with newlines without showing backslash escapes in gdb?

Update:
Why not just use the gdb printf command?

(gdb) printf "%s", x
asd
qwe
...
(gdb)

Old answer:
From within the debugger you can execute commands. Just call printf

(gdb) call printf("%s", x)
asd
qwe
...
(gdb)
