This fixes a false positive reported by revive on the following:
select {}
This is a way to block the program indefinitely.
It is used in cases like:
- Running a long-running server in a background thread
and blocking `main` from exiting until the application dies.
This is something you might do if your process has
multiple servers/listeners in the same process.
```go
go grpcListenAndServe()
go httpListenAndServe()
go logFlusher()
select {}
```
- In programs compiled to WASM to prevent the application from exiting,
so that the Javascript components may interact with it.
```go
func main() {
js.Global().Set("foo", foo)
select {}
}
```
Without this, one may see an error like,
"Error: Go program has already exited"
As a workaround, these programs can block forever
by receiving from a throwaway channel (`<-make(chan struct{})`),
but `select {}` is still a completely valid way of doing this,
so supporting it makes sense.
The issue was previously reported in #698 but was closed
because the author was satisfied with a `//nolint` comment.
Now that this rule is part of the default rule set (#799)
the case for addressing the false positive is stronger.
