I omitted a lot of the min/max modernizers because they didn't result in more clear code. Some of it's older "for x := range 123". Also: errors.AsType, any, fmt.Appendf, etc. Updates #18682 Change-Id: I83a451577f33877f962766a5b65ce86f7696471c Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
