Agreed, changing it will probably break something. Could it be that
the empty line was included so that in a sequence of defuns (each
normally separated by one empty line) mark-defun could by used, for
example in combination with kill-region and yank to move around
defuns in a simple way?

No matter whether something like that or anything else was the
actual reason for implementing this behavior, the docstring should
always document the actual behavior
