Initially I didn’t have this restriction, but it doesn’t work well together with some multi-line logging.
See below for an example.

To get this nice, it would require a larger amount of changes, and probably result in something that nobody wants to merge in.

Anyway, there’s a flag controlling this behavior and if you really want, you can set it.
Then you’ll see something like this:
