[Doxygen-develop] don't put closing parenthesis on its own line

[Anthony F. <ant...@gm...>]

Greetings.

I don't know if it is intentional or not, but I found that the current
Doxygen output for multiple (2-or-more) argument functions to be
sub-optimal.  It wants to render it like so:

retType
myFunction( Type1 arg1,
          Type2 arg2
          )

In case that formatting gets mangled, you can see the difference in
this sample page, pointed out by PovAddict:

   http://www.stack.nl/~dimitri/doxygen/manual/examples/overload/html/class_test.html
   or: http://preview.tinyurl.com/avovthd

I don't see any reason for this extra space, not even "const" or
similar.  After all, 0- and 1-arity functions don't get the extra
space.

And I personally dislike the aesthetic, although I can appreciate that
this is less clear-cut, and that others might have other opinions.
(As PovAddict said on IRC: "for something like this, you'll get
bikeshedding no matter where you post it"...)

Anyway, I cooked up a small patch to get rid of the extra space.  As a
bonus, it is a net removal of lines of code.  Please feel free to
incorporate or discard.

Thanks, either way, for a fantastic tool.

Best regards,
Anthony Foiani
