Details:

Grub 2.0 does not escape the ${GRUB_DISTRIBUTOR} variable properly for the
class parameter.
If the variable consists special characters like apostrophes the grub.cfg
can't be parsed because of syntax errors on the next boot.

For example:
 menuentry 'Tim'\''s JeOS, with Linux 3.7.6-1.2-default (recovery mode)'
--class tim's --class gnu-linux --class gnu[....]

The attached patch fixes the issue by replacing all special characters with
"-".
