Auto merge of #106352 - kornelski:read_line-doc, r=scottmcm
Document read_line gotchas 1. The "You do not need to clear the buffer before appending" advice is ambiguous, because it depends what you use this function for. For a rather common case of reading individual lines in a loop, it _is_ necessary to clear the buffer. 2. The docs warn about a DoS risk. I've added a hint how to mitigate unbounded memory growth.
