>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:
/usr/bin/printf %u%u 15
(should output 150)
