I was looking for a simple solution I could apply to join/concatenate 3 lines of text together using Vim. I wanted to take a file containing 36 short strings and join every 3 lines, in effect producing just 12 longer lines. (For anyone reading this and wondering why - I was producing a markdown table around some shortcut commands). So the example is, I had wanted to take:
1 short-line one
2 short-line two
3 short-line three
and have:
1 short-line one 2 short-line two 3 short-line three
across the file.
