When the jump instruction is displayed at the row 0 in annotate view,
the arrow is broken. An example:
16.86 │ ┌──je 82
0.01 │ movsd (%rsp),%xmm0
│ movsd 0x8(%rsp),%xmm4
│ movsd 0x8(%rsp),%xmm1
│ movsd (%rsp),%xmm3
│ divsd %xmm4,%xmm0
│ divsd %xmm3,%xmm1
│ movsd (%rsp),%xmm2
│ addsd %xmm1,%xmm0
│ addsd %xmm2,%xmm0
│ movsd %xmm0,(%rsp)
│82: sub $0x1,%ebx
83.03 │ ↑ jne 38
│ add $0x10,%rsp
│ xor %eax,%eax
│ pop %rbx
│ ← retq
The patch increments the row number before checking with 0.
