Have a look at Reformat → Method Signature in the Objective-C  
bundle. It doesn’t do your style by default, but you can modify the  
script (I have done that locally to get my style) — then one can  
just press ⌃Q on a method signature (be it in the interface or  
implementation) and get it reformatted properly.

I use that a lot when pasting methods from the Cocoa documentation :)

The problem with the “Next” + “Replace” is the look-ahead.  
The “Replace” is not connected with the previous “Next” and so  
will replace the selection with the contents of the replace string,  
regardless of what caused the seletion — for your regexp this will  
fail, because the selection no longer matches the find pattern  
(because of the look-ahead).

So all in all, it shouldn’t really work that way, but does for  
technical reasons.
