> 1. end-of-story is different from end-of-paragraph
> From document of ITextDocument::GetStoryCount: Rich edit controls have
only one story.[1]
> So ‘story’ may is an unit like 'paragraph' in Rich edit control. We may
need add a MERF_ENDSTORY to implement it.[2]
> 2. What does the end-of-story looks like?
> When we run the wordpad with native riched20, we can use ‘ctrl + shitf +
→’ to select the ‘space’ at the end of the Rich edit control. But we cannot
set the cursor behind it.(a picture here[3])
> And wine’s riched20 didn’t implement this ‘space’. This 'space' may is
the end-of-story.
> A crash will happen when we copy the ‘space’ from a native Rich edit
control to a builtin one.(backtrace.txt[4])
> BTW, there is a know bug of EM_SETSEL: cannot select the last character
of Rich edit control.[5]
> 3.
> From the last paragraph of this blog:
> It is sure there is a final EOP in a Rich edit control.
> There seems to be every indication that we should implement the final EOP
of Rich edit control rather than just append a ‘\r’ in
> So I just let a FIXME comment there. I am not sure if I am right.
