Public bug reported:
Busybox‘s implementation of `ed` skips a line when inserting. It will
insert the first line before and all subsequent lines after the line
addressed.
gnu ed implementation behaves like expected:
```
$ ed
i
one
two
three
four
five
.
,p
one
two
three
four
five
1
one
i
ione
itwo
ithree
ifive
.
,p
ione
itwo
ithree
ifive
one
two
three
four
five
Q
```
The lines »ione« through »ifive« are inserted before the line »one«. But
busybox’s behaviour differs:
```
$ busybox ed
: i
one
two
three
four
five
.
: ,p
one
two
three
four
five
: 1
one
: i
ione
itwo
ithree
ifour
ifive
.
: ,p
ione
one
itwo
ithree
ifour
ifive
two
three
four
five
: q
Really quit? y
```
The line »ione« is inserted before »one« and the lines »itwo« through
»ifive« are appended after »one«. However, `append` works as expected.
