[PATCH 4/5] riched20: Implement ITextRange::Collapse. (try 2)

[Indrek Altpere]

This seems to be a typo, I think the original variable name was mean to be
isedge or is_edge.
Perhaps this check would be simpler to understand and would not create local
variable if it were like this?

if (*end == *start)
    return S_FALSE;
