[patch] Fix applying changes at EOF

[Piotr Piastucki <leech miranda gmail com>]

Hi,

There is one more (hopefully the last one :)) issue with applying insertions at EOF that results in unexpected line concatenation. 
The attached patch fixes the issue by prepending a newline character. See http://piastucki.bdl.pl/meld/apply_change_at_eof.png for a screenshot.

Cheers,
Piotr
