You are correct that rhsc doesn't match the dot, which is fine, because
rhs says that your string from rhsc must be followed by a dot.

That is:

     {rhsc} "." {*}

       {rhsc}  accepts "baylink"
       "."     accepts "."
       {*}     accepts the trailing spaces

     End-of-edit and end-of-field reached.  Edit passes.
