It does that only for the last line, e.g. the register contains
"foo\nbar\n" then Vim will insert into the buffer foo\nbar and the
operation will be linewise. But when evaluating an expression and the
return string from the eval0() call returns foo\nbar\n you want the put
to insert the trailing last line.
