Huw Davies (@huw) commented about dlls/riched20/run.c:
do { para->nCharOfs += shift;
/* update position in marked tree, if added */
if (para->nFlags & MEPF_REWRAP)
{
para_mark_remove( editor, para );
para_mark_add( editor, para );
}
I guess we'd also want `para_mark_remove()` to use `wine_rb_remove()` rather than `wine_rb_remove_key()`.
