Humble Chirammal 323cc0e3bb cleanup: avoid comparing errors directly
Go 1.13 contains support for error wrapping. To support wrapping,
fmt.Errorf now has a %w verb for creating wrapped errors, and three
new functions in the errors package ( errors.Unwrap, errors.Is and
errors.As) simplify unwrapping and inspecting wrapped errors.

With this change, If we currently compare errors using ==, we have to
use errors.Is instead. Example:

if err == io.ErrUnexpectedEOF

becomes

if errors.Is(err, io.ErrUnexpectedEOF)
