Won't the extra '\n' result in a weird extra blank line when printing just the file headers?

I also noticed that there was a lot of inconsistency between the different outputs in this area. What I'd like to see is each different dump to append a blank line, only if there is more to come.

I don't feel too strongly about it though, as long as we are consistent.

With that change it becomes consistent with what is done for COFF:
https://github.com/llvm-mirror/llvm/blob/master/tools/llvm-objdump/llvm-objdump.cpp#L2437

It prints an additional empty line after "start address" but does not seem it look too bad perhaps:
(I mean the last extra line, the first one looks a bit wierd to me, but it was already there).

umb@umb-virtual-machine:~/LLVM$ /home/umb/LLVM/build/bin/llvm-objdump ooo --file-headers

ooo: file format ELF64-x86-64

architecture: x86_64
start address: 0x0000000000201000

umb@umb-virtual-machine:~/LLVM$ /home/umb/LLVM/build/bin/llvm-objdump ooo --section-headers

I am also noticed a few inconsistencies (and also code style issues), but I think it is better to fix/refactor in a separate patch(es),
all at once perhaps.
