[tex-live] tlmgr warning with perl 5.22.0

[Konstantin Belousov]

With perl 5.22.0, I get the following warnings on update:

tlmgr: package repository http://mirror.datacenter.by/pub/mirrors/CTAN/systems/texlive/tlnet
tlmgr: saving backups to /usr/local/opt/texlive/2015/tlpkg/backups
Redundant argument in sprintf at /usr/local/opt/texlive/2015/bin/i386-freebsd/tlmgr line 3109.
[ 1/15, ??:??/??:??] update: animate [3108k] (36484 -> 37617) ... done
Redundant argument in sprintf at /usr/local/opt/texlive/2015/bin/i386-freebsd/tlmgr line 3109.
[ 2/15, 00:05/00:34] update: biblatex-opcit-booktitle [93k] (37533 -> 37618) ... done

It seems to be cosmetic.
