2022-06-04io: revert: add an Err field to LimitedReaderRuss Cox
We are having a hard time deciding the exact semantics of the Err field, and we need to ship the beta. So revert the Err field change; it can wait for Go 1.20. For #51115. This reverts CL 396215.

2020-10-20all: update references to symbols moved from io/ioutil to ioRuss Cox
The old ioutil references are still valid, but update our code to reflect best practices and get used to the new locations. Code compiled with the bootstrap toolchain (cmd/asm, cmd/dist, cmd/compile, debug/elf) must remain Go 1.4-compatible and is excluded. Also excluded vendored code. For #41190.

2020-10-20io: adopt Discard, NopCloser, ReadAll from io/ioutilRuss Cox
As proposed and approved in #40025, Discard, NopCloser, and ReadAll do not really fit into io/ioutil, which exists mainly to hold things that would cause an import cycle if implemented in io itself, which is to say things that import "os". These three do not import "os" - they are generic io helpers like many of the things in io itself, so it makes sense for them to be there. Fixes #40025.

2017-07-15io: Add example to io.Seeker's Seek() method.Greg Poirier
While there's an example for SectionReader.Seek, if someone is seeking documentation specifically about Seeker.Seek, they may not immediately find the SectionReader example. Offset and whence may not be entirely intuitive to new developers either, so include examples of both positive/negative offsets and SeekStart/SeekEnd.
