  fix issue 15293

ReadlnAppender tried to claim the capacity of the passed buffer, calling
assumeSafeAppend on the result so that on the next call it has a capacity
again that can be claimed.

The obvious problem with that: readln would stomp over memory that it has
not been given.

There was also a subtler problem with it (which caused issue 15293):
When readln wasn't called with the previous line, but with the original
buffer (byLine does that), then the passed buffer had no capacity, so
ReadlnAppender would not assumeSafeAppend when slicing the new line from
it. But without a new assumeSafeAppend, the last one would still be in
effect, possibly on a sub slice of the new line.
