* util/mkisofs/write.c (padblock_write): Switch size and nmemb
arguments to fread so that we get a return value in bytes, rather
than something that will normally be rounded down to 0.
Adjust error handling to avoid producing garbage when size_t is not
the same size as long long.
* util/grub-mkconfig_lib.in: Don't set grub_probe or grub_mkrelpath
if they're already set. This resolves the conflict between my
grub-install change on 2009-10-06 and Felix' change on 2009-11-11,
fixing the --grub-probe option again.
* util/sparc64/ieee1275/grub-install.in: Revert the last piece of my
change on 2009-10-06, so that we now once again source
`${libdir}/grub/grub-mkconfig_lib' after options have been parsed.
