In perl5.004_05, printf stopped working right with $x.0d when 0
is the value. In 5.004_04 it worked.

In perl5.004_05, printf stopped working right with $x.0d when 0
is the value. In 5.004_04 it worked.

defender​:~> perl -e 'printf "$]​:%4.0d\n", 0'

rock% perl -e 'printf "$]​:%4.0d\n", 0'
5.00404​: 0

This was deemed a bug in 5.004_01, but I'm not sure if the special
case is actually mandated by a standard. See​:
