Have you verified that the file actually gets changed with the
$curbuf->Delete() call? I would be surprised if it did, since your
syntax is invalid.
$curbuf->Delete() only takes one or two integer arguments: A single
integer deletes the corresponding line; Two integers deletes a range
of lines. See ":help perl-Delete".
In other words, this:
$curbuf->Delete(1 .. $curbuf->Count());
Should be this:
$curbuf->Delete(1, $curbuf->Count());
When I change your sample of code accordingly, I always get what I
expect ("$curbuf->Count() after delete: 1").
