>Description:
/usr/bin/printf %u%u 15
Actual output: "1515"
Expected output: "150"
POSIX specifies that extra format specifiers shall be treated as zero:
http://mid.gmane.org/201212171135.14216.Arfrever.FTA@gmail.com
dash,bash,zsh, as well as Solaris and Linux, print "150". But printf(1) on FreeBSD prints "1515".
Reproduced by eadler@ on -CURRENT.
>How-To-Repeat:

(should output 150)
