vim-add-blank-lines.md

Insert blank lines only where there is not blank line

This solution will avoid double blank lines

:g/.\n\n\@!/norm o

The magic happens because we are denying a consecutive new line with \n\@!

Insert a blank line after each second line

:%s/^/\=(line(".")%3==0?"\n":"")/g

The first parentesis is a ternary operator wich will retun a new line "\n" or a blank line "" depending on the Mod of the line number line(".") by 3. In case it is true the beginning of line is substituted by a new line.
