Yep, that was me that rejected the edit.

I did so because on the Markdown edit viewer (which is where I look at edits) all you see is this:

From that it looked like all you had done is change "batchfile" to "batch file" in a few places and add a single code quote conversion.  This does not meet my criteria for making a good improvement to the post.

It's not until you look at the rendered view that you see this:

Which is, as you say, actually an improvement in readability.

I'm still torn on whether or not you did "enough" to improve the post.  I can see a few things I might have removed or altered: the brackets in the second paragraph are a bit superfluous and there might have been some other improvements that could be made.

As it is If I saw it again, I'd be unsure to let it through with only the two edits you did.
