correct.

with "/^\n*$".

That would be possible, but doesn't really change the cursor motion. Take
the example from the patch:
----------------------------
1 Lorem ipsum dolor sit amet,
2 consetetur sadipscing elitr,
3 sed diam
4
5
6 Lorem ipsum dolor sit amet,
7 consetetur sadipscing elitr,
8 sed diam

If the 'para' option is set to '/^$' moving using '}' will first move to
line 4, the next paragraph motion will move to line 5. Typing '}' again
will then move the cursor at the end of the last line.
--------------------------

Even is you use the /^\n\+$ as regular expression, the cursor will still
jump to the exact same positions, as line 4 and line 5 match
that regular expression. We could make it jump to the end of the match
using the SEARCH_END flag and then advance the cursor one more position,
but this would only work on forward searches, this doesn't seem to work
for backward searches:
