Martin Garton e51b19a993 bufio: make Reader.Peek invalidate Unreads ... Since Reader.Peek potentially reads from the underlying io.Reader, discarding previous buffers, UnreadRune and UnreadByte cannot necessarily work. Change Peek to invalidate the unread buffers in all cases (as allowed according to the documentation) and thus prevent hiding bugs in the caller. (This change was previoiusly merged and then reverted due concern about being too close to a release) Fixes #18556 Change-Id: I9027d75aa834d4b27703f37711ba25de04d89f3c GitHub-Last-Rev: 917ef1e511 GitHub-Pull-Request: golang/go#28768 Reviewed-on: https://go-review.googlesource.com/c/149297 Run-TryBot: Ian Lance Taylor <iant@golang.org> TryBot-Result: Gobot Gobot <gobot@golang.org> Reviewed-by: Ian Lance Taylor <iant@golang.org>		2018-11-13 15:08:13 +00:00
