Subject: bug#10782: zero padding does not work in case of strings

From: Praveen A <[email-masked]>

$ printf %04d 12
0012$ printf %4d 12
  12$ printf %04s 12
  12$ printf %4s 12
  12$

It would be very useful if it works for strings too (I found this when
trying to zero pad hex values in an ipv6 address). Now it requires an
additional sed find and replace to get the desired result.

Thanks
Praveen

You have to keep reminding your government that you don't get your
rights from them; you give them permission to rule, only so long as
they follow the rules: laws and constitution.
