bug#12369: 24.2.50; cl-loop: variable not left unused

[Christopher Schmidt]

severity: minor

    ;; -*- lexical-binding: t -*-

    (require 'cl-lib)
    (cl-loop for (rms . emacs) in nil)

Byte compile this piece of code.

    Warning: Unused lexical variable `rms'

Attempting to fix this warning by renaming rms to _rms results in
another warning.

    Warning: variable `_rms' not left unused
