consider linking to specific line numbers

[lolbinarycat]

I noticed this issue in this comment where the diff output is cut off just one line too early. if each group contained a link to its first line, i could easily navigate to the relevant log line and see what file the diff occured in.

additionally, --- is not a clear indicator for "some output has been omitted here", as --- also is a common part of diffs. more clear would be having each chunk in a separate code block, with line-number links in-between.
