You can clone with
enter the following text:
Line one here
Line two here
Then, yy the first line.
Visually select the second line with V.
Then paste while visually selecting the second line.
There will be an extra line that Vim doesn't seem to add.
fixes #166 - improve pasting in visual line mode
Woohoo! Works perfectly - even leaving the cursor in the same position that Vim would leave it in.
