Add comment lines above and below?

[AndrewB]

I'm wondering if there is a way to automatically add a comment line above and below a text block or line that is merged to another file. If not, does anyone have a special way they do this to make it easier. The type of comment lines I have in mind are something like this:

// BEGIN XYZ MOD
merged code
// END XYZ MOD

There isn't a way to do this in the current version of BC. I will add it to the wish list.
