    patch 8.1.0125: virtual edit replace with multi-byte fails at end of line

    Problem:    Virtual edit replace with multi-byte fails at end of line. (Lukas
                Werling)
    Solution:   use ins_char() to add the character. (Christian Brabandt,
                closes #3114)  Rename PCHAR() to PBYTE() to avoid mistakes like
                this.
