Quick answer. I think you can work around this by refiling however you want, perhaps with your own wrapper command or a rebinding, then simply C-c C-c the blank capture buffer. For example, activate the region.
(I heard that C-c C-w in capture is a special thing that only works on one thing to be refiled. This is be in the manual either way.) That is what I do and it works perfectly, with no blank line issues. If this is the issue, maybe the special thing in capture is more of a newcomer trap than it's worth for experts?
