For the use of {buf}, see |bufname()|.
{lnum} is used like with |append()|. Note that using |line()|
would use the current buffer, not the one appending to.
Use "$" to append at the end of the buffer.
{lnum} is the line number to append below. Note that using
|line()| would use the current buffer, not the one appending
to. Use "$" to append at the end of the buffer. Other string
values are not supported.
On success 0 is returned, on failure 1 is returned.
In |Vim9| script an error is given for an invalid {lnum}.
