I can see where this would be a problem.  printk() is minimal and
the only real requirements are to print what the tests require.
I am fixing this on both the trunk.  Your local version of 4.5
must have an updated printk because the official 4.5 did not
include width support in printNum().

This doesn't surprise me since printk hasn't had any real bug reports
against it.
