I think that will all be attributable to the style of the author for
those parts of the code.  It looks to me that originally the code used
a mixture of printf and fputs calls and that the calls that simply
outputed a blank line were recently changed to be a puts call instead.
It is shorter, so I imagine that is why it was done.

There isn't any effective difference.  It would simply be a matter of
style and taste.  Both call the standard I/O libc functions and libc
will end up doing the same thing in both cases.
