Extra blank line shown at end of files

Description

Any file that ends in a single \n (so no visible trailing newline in text editors) seems to have an extra blank numbered line shown when viewing it from Gitea on web. I'm posting this as a new issue as #4050 is closed and locked but it appears to have regressed.

I can't seem to reproduce this on try.gitea.io so perhaps it's been fixed in dev already, but on a quick search I haven't found any recent commits or issues relating to this.

Can you try it with 1.18 (https://try.gitea.io)?

I think the problem has a clear solution now (but not in 1.17, due to some long argument before 1.17's freezing)

• Rework file highlight rendering and fix yaml copy-paste #19967
• Remove final newline from rendered code #18076 (comment)

Yeah seems fine there, didn't spot that this was explicitly addressed recently.
