diffWords treats \n at the end as significant whitespace

[OleMchls]

we have the following behavior:

coffee> diff = require 'diff'

# works as expected
coffee> diff.diffWords("hase igel fuchs", "hase igel fuchs")
[ { value: 'hase igel fuchs' } ]

# newline at righthand results in a change
coffee> diff.diffWords("hase igel fuchs", "hase igel fuchs\n")
[ { count: 5, value: 'hase igel fuchs' },
  { count: 1, added: true, removed: undefined, value: '\n' } ]

# newline at lefthand results in a change
coffee> diff.diffWords("hase igel fuchs\n", "hase igel fuchs")
[ { count: 5, value: 'hase igel fuchs' },
  { count: 1, added: undefined, removed: true, value: '\n' } ]

# newline in the middle words also as expected
coffee> diff.diffWords("hase igel fuchs", "hase igel\nfuchs")
[ { value: 'hase igel\nfuchs' } ]

when we read the documentation right, every whitespace should be ignored when using diffWords.

Any thoughts on that?
