Bug#79515: grub-install fails with floppy

[Bastian Kleineidam]

Package: grub
Version: 0.5.96.1


Hi Gordon,

running grub-install with a floppy target fails (/floppy ismounted on
/dev/fd0)
[...]
address@hidden://usr/sbin> grub-install --root-directory=/floppy '(fd0)'
/usr/sbin/grub-install: -e: command not found
/usr/sbin/grub-install: -e: command not found
expr: non-numeric argument

    GRUB  version 0.5.96.1  (640K lower / 3072K upper memory)

 [ Minimal BASH-like line editing is supported.  For the first word, TAB
   lists possible command completions.  Anywhere else TAB lists the possible
   completions of a device/filename. ]

grub> root (fd0,)

Error 12: Invalid device requested

grub> setup  --stage2=/floppy/boot/grub/stage2 --prefix=/boot/grub (fd0)

Error 12: Invalid device requested

grub> quit
address@hidden://usr/sbin> 
[...]

I have an uptodate woody system, running on 2.2.17 Intel architecture.

The following patch makes two things:
a) insert set -e because if something goes wrong, the following grub
   command can be very dangerous.
b) correct 'sed' statements when stripping device parts
