Neovim support: line buffers shouldn't contain newlines

The result of `difflib.unified_diff()` may contains newlines at the end of its
each line. It's suppressed in original Vim, but it's illegal in Neovim.

Since there is no good way to prevent `difflib` from appending newlines to the
results, `_output_preview_text()` function should sanitize it.

Thanks @michamos
