Comment # 3 on bug 1086766 from Marketa Calabkova

I have created the pull request:
https://github.com/karelzak/util-linux/pull/766. It did not hurt and if it had
been created a year ago, the change could have possibly made it to
SLE15/Leap15. Do not hesitate to create pull requests even regarding such small
fixes, it is much more comfortable for the developers.
