All the single quotes are written as `\'` in the descriptions. I assume
that's for a good reason, but -list-checks would print:

    % staticcheck -list-checks | grep "'"
    S1003 Replace call to \'strings.Index\' with \'strings.Contains\'
    S1004 Replace call to \'bytes.Compare\' with \'bytes.Equal\'
    S1011 Use a single \'append\' to concatenate two slices
    S1012 Replace \'time.Now().Sub(x)\' with \'time.Since(x)\'
    ...

    % staticcheck -explain S1003
    Replace call to \'strings.Index\' with \'strings.Contains\'

So fix that:

    % staticcheck -list-checks | grep "'"
    S1003 Replace call to 'strings.Index' with 'strings.Contains'
    S1004 Replace call to 'bytes.Compare' with 'bytes.Equal'
    S1011 Use a single 'append' to concatenate two slices
    S1012 Replace 'time.Now().Sub(x)' with 'time.Since(x)'
    ...

    % staticcheck -explain S1003
    Replace call to 'strings.Index' with 'strings.Contains'

The Before and After had extraneous newlines; before:

    % staticcheck -explain S1000
    Use plain channel send or receive instead of single-case select

    Select statements with a single case can be replaced with a simple
    send or receive.

    Before (· represents blank line, git strips double blanks otherwise):
        ·
        ·
        select {
        case x := <-ch:
            fmt.Println(x)
        }
        ·
    After:
        ·
        ·
        x := <-ch
        fmt.Println(x)
        ·

And after:

    % staticcheck -explain S1000
    Use plain channel send or receive instead of single-case select

    Select statements with a single case can be replaced with a simple
    send or receive.

    Before:

        select {
        case x := <-ch:
            fmt.Println(x)
        }

    After:

        x := <-ch
        fmt.Println(x)
