unless is a Lisp macro in `subr.el'.
(unless COND BODY...)
If COND yields nil, do BODY, else return nil. <--------what is this line doing here?
When COND yields nil, eval BODY forms sequentially and return
value of last one, or nil if there are none.

The same happens for `when', BTW.
It's not a bug. Most docstrings are written so the first line provides
a summary of the corresponding function/macro/special form/variable.
This makes the output of apropos more useful.

It's the one-line summary of the function. Every docstring has one.

Well e.g., man pages have headers "SUMMARY" etc. separating the different
parts. If the rendering jammed them all together it would look bad.
Even in debian apt there is indentation:
