I was just think that https://github.com/llvm/llvm-project/blob/88c4ef2f9fc0cda90c8452bc1c46844aaa722a3e/lldb/source/Commands/Options.td#L1139 doesn't mention that the leading `+` is supported or that the value can be negative. Also I can't tell, at least from the help text, if this includes whitespace or not. 

Like if I had:
```
  int a = 3;
  a = 1;

  a = 2; //<pc=here> thread jump -b -1 does this go to the blank line?
```
