next_boundary() panics when cursor is at the end of the given chunk #135
Description
Hello,
In prev_boundary we have this check (for the following unwrap not to panic):
if self.offset == chunk_start {
return Err(GraphemeIncomplete::PrevChunk);
}I suggest this in next_boundary() (for the same reason):
if self.offset == chunk_start + chunk.len() {
return Err(GraphemeIncomplete::NextChunk);
}Thank you!
