When motion is 'word' and evil-want-change-word-to-end is t, behave like 'ce', not 'cw'

This seems like a simple solution to #117

@ninrod let me know if you think this approach is OK, and I'll add tests.

120 should probably be merged first though, so we get better test coverage when this is merged.

@edkolev, yes, I think it is a nice approach. Please let's add tests to this pull!

I've just merged #120

While adding tests, I found this issue:

• with hello [w]orld
• ysw'
• results in hello 'worl'd, which is incorrect

Another issue:

• with [h]ello world
• ysw'
• results in 'hello ' world, which again is wrong

I'll let you know if I get this sorted.

@edkolev, awesome that the test discipline helped to catch that.

Closing, see #122
