While it is nice to add some spacing and make things a bit easier to read, I don't really see the point in this.
If you want it to be easily parsable by a human then there are hundreds of applications designed for this. The most common being spreadsheets like Excel.
And what happens if you have a list of domains, but one contains a really long url (300 characters wide?). It will mess up the columns for every single row above and below it as well.
Also adding comments will completely break any existing software (I think most programs can handle some more whitespace, but you couldn't import the final example into Excel, I don't think (untested))
