fix problem where displaying multiline regexes that have their start on
one page of a line and their end on a different page of the same line
would paint past the end of the regex by tweaking DB's changes to add
multibyte string support to edit_add(); now calculate paintlen the same
way the original working code did, but keep accounting for multibyte
characters as DB'S new code did
