richedit: Avoid rewrapping all text for isolated format changes.

When the character or paragraph format is changed the paragraph that is
changed is already marked to be rewrapped, so ME_MarkAllForWrapping
shouldn't be called.  Since ME_RewrapRepaint uses this function, it
shouldn't be called in these circumstances, since rewrapping all the
text can cause noticable delays when working with a lot of text.

The problem this patch fixes can be seen by opening up a large text file
in wordpad, selecting a single word, then making that word bold.  This
can cause quite a needless delay for a very large file.
