Subject: vim-patch:9.1.0426: too many strlen() calls in search.c

Solution: refactor code and remove more strlen() calls,
          use explicit variable to remember strlen

Subject: vim-patch:9.1.0428: Tag guessing leaves wrong search history with
 very short names

Problem:  Tag guessing leaves wrong search history with very short names
          (after 9.1.0426).
Solution: Use the correct variable for pattern length (zeertzjq).
