		Title: `Unnecessary guard around map access`,

		Text: `
When accessing a map key that doesn't exist yet, one receives a zero
value. Often, the zero value is a suitable value, for example when
using append or doing integer math.

The following

    if _, ok := m["foo"]; ok {
        m["foo"] = append(m["foo"], "bar")
    } else {
        m["foo"] = []string{"bar"}
    }

can be simplified to

    m["foo"] = append(m["foo"], "bar")

and

    if _, ok := m2["k"]; ok {
        m2["k"] += 4
    } else {
        m2["k"] = 4
    }

can be simplified to

    m["k"] += 4
