For example, if the directory `6-stdlib/99-minor` is present,
then an `api/next` file with the line

    pkg net/http, function F #12345

should have a corresponding file named `doc/next/6-stdlib/99-minor/net/http/12345.md`.
At a minimum, that file should contain either a full sentence or a TODO,
ideally referring to a person with the responsibility to complete the note.

        else "<unknown>" // It's a source distribution, we don't know.
    }
}

fun toMergeQueueBaseBranch(actualBranch: String): String = when {

The [Alias] type now has an [Rhs] method that returns the type on the
right-hand side of its declaration: given `type A = B`, the `Rhs` of A

    serverWriter.writeMessageFrame(OPCODE_TEXT, payload)
    assertData("8105")
    assertData(payload)
  }

  @Test fun serverLargeBufferedPayloadWrittenAsOneFrame() {
    val length = 12345
    val payload: ByteString = (binaryData(length))
    serverWriter.writeMessageFrame(OPCODE_TEXT, payload)
    assertData("817e")
    assertData(format("%04x", length))
    assertData(payload)
  }
