 If you want to handle both stderr and stdout with one handler use the
 "callback" option: >
-    let job = job_start(command, {"callback": "MyHandler"}) 
+    let job = job_start(command, {"callback": "MyHandler"})
 
 Depending on the system, starting a job can put Vim in the background, the
 started job gets the focus.  To avoid that, use the `foreground()` function.
