Patch for printf's "%If"

[Hamed Malek]

Attached is a patch for "%If" (and other similar) format strings to work
with printf and other such functions. This is required for Persian and
other locales which use localized digits (outdigit).  Currently, the 'I'
prefix works for decimal integers, which should be extended to decimal
floats.

I appreciate the patch being included. I consider the patch public domain. 
But please tell me if I need to sign a copyright assignment to FSF.
