Doesn't it depend on what tag you're inserting whether it's likely you
want to have a newline at the end, though?  The more "block"-like tags
would normally be preferably have a newline at the end, while others
don't.

On the other hand, if you're inserting a tag in the middle of the line,
you probably don't want to insert a newline, I think?  So perhaps just
adding that defcustom is the right option...
