This modification allows you to see the highlighted source of Snippets, Chunks, and Templates with line numbers using the Geshi Highlighter. I have found this to be extremely helpful when creating snippets due to the line numbers, and it just makes the code easier to decipher (my opinion
)
There are a couple of minor core file changes but very minimal and I commented the areas that were added. In case of newer core versions of the altered files, transfer a couple of lines of code and thats it.
Included in the zip file is a file named "readme706_805am.txt" which has detailed install instructions and a list of the files which are affected. I’ll also attach the readme file here seperate in case you want to read it before you download the zip.
Here are a couple of screenshots to show how it looks:

Hopefully this will be useful to some folks...
