compatibility with older vim?

[mg979]

Is there a reason why it's using getbufline() and related functions, instead of getline()?
Are there cases where the working buffer is not the current buffer?

I want to work in older vim too.
But 'deletebufline' can not replace to compatible code, I think. (appendbufline is replaceable to append...)

I think cursor is always on the working buffer.

Instead of deletebufline() you can use delete, example:

call deletebufline(bufnr, start, end)

becomes (using :delete and a range)

exe start . ',' . end . 'delete _'

where _ means to the black hole register (so that no registers are overwritten).

Thanks! I try it.

Thanks.

I've supported older vim!
