[PATCH] Making use of argp in GRUB utilities

[Lubomir Kundrak <lkundrak@redhat.com>]

Hi,

I've noticed, that GRUB 2 uses argp in grub-emu [1], whereas other
utilities use getopt_long [2]. Wouldn't it be nice to make this
consistent?

I find the "GNU way," argp, approach more elegant, as demonstrated by a
patch to util/i386/pc/grub-mkimage.c. Seeing a patch with more minuses
than pluses is a good sign, indeed.

The main argument against agrp framework could be, that non-GNU C
libraries do not contain with it. There's a standalone libargp package
[3] that is available for package systems of all major operating
systems, including NetBSD and FreeBSD, so the only disadvantage is
addding a dependency there.
