[UI] 70 char edit blob commit message marker falls out of the textarea when screen around 620px.

Check out the marker at the right outside of the textarea and before the scrollbar:
The question here is that this textarea sizes down, which is desirable to avoid https://github.com/gitlabhq/gitlabhq/issues/7484.
As a possible implementation, note that the width marker given to the content by ACE editor works correctly and disappears.
