The purpose is not really to make it configurable, but to isolate the
code that provides this part of the functionality.

Right, I was thinking about the case in my suggestion of highlighting
the closing paren in at the end of the previous line.

I think the :prefix only makes sense for defgroup, not for defcustom.
Many keywords are like that, so maybe defgroup shouldn't delegate to
defcustom's docstring.
