Bug#646788: grub-mkrescue: --xorriso=... broken

[Philipp Matthias Hahn]

Package: grub-common
Version: 1.98+20100804-14+squeeze1
Severity: normal

"grub-mkrescue --xorriso=..." is handled differently than
"grub-mkrescue --xorriso ..."; notice the '='.

In the former case a trailing slash '/' is added, which looks like an
upstream bug. This bus is still present in grub_1.99-12 from Debian-sid.
