patch 9.1.1322: small delete register cannot paste multi-line correctly

Problem:  small delete register cannot paste multi-line correctly
          (after v8.2.2189)
Solution: caused by 032a2d050b82b146d70d6ff714838ee62c07d8ad, so make
          this logic handle charwise only (phanium)

closes: #17151
