Highlights when you do what? Are you talking about a simple / search or a syntax highlight or something else?
> but when I check the match and matchend in order to copy the matches, it does include the "-" between 3-4 4-5 5-6 6-7 7-8
match() and matchend() are functions which work on a string, they don't look at buffer text. In what way did you use these on the text? How do you know it includes the "-"? Or are you referring to something other than match() and matchend()?

They should. Please give the EXACT command you ran, and tell exactly what you expected, and exactly what happened instead. A script which will reproduce what you see would be best.
