Description of problem:
I have a line in /boot/grub/grub.conf that specifies terminfo grub
should use (the purpose is to have fancy colors on the serial console):

terminfo --name=linux --cursor-address=\E[%i%p1%d;%p2%dH \
--clear-screen=\E[H\E[J --enter-standout-mode=\e[33;44;1m \
--exit-standout-mode=\e[39;49;22m

After running "make install" in the kernel directory, the expression
after cursor-address is mangled:

terminfo --name=linux \
--cursor-address=\E[1345734640x80561781134568072;0x8052ab22-1073746488H
...

This happens because grubby uses printf without an explicit format,
assuming that there are no C formatting directived in grub.conf.  Not
only is it wrong, but it might crash grubby in some cases.


Version-Release number of selected component (if applicable):
mkinitrd-4.1.18-2

How reproducible:
Always

Steps to Reproduce:
1. Add line containing "# %s" in /boot/grub/grub.conf
2. Install a kernel from sources by running "make install".
3. See /boot/grub/grub.conf
    

Actual Results:  The line becomes "# (null)"

Expected Results:  The line should remain "# %s"
