I don't think breaking up the lines is advantageous. It makes it more complex to read, and doesn't really provide any benefit. Maybe if the line was full of lots of command line params:

```
foo -i butts\
  -e blergh\
  -j "look at my long string that is loooooooong"
```

But I don't think these urls go much over the 140 character line that would really make them need to be broken up.
