Bug#530736: grub-common: error:unknown command `true'

[darren]

Package: grub-common
Version: 1.96+20090523-1
Severity: minor

this error message shows quickly before menu list shows
this line in /etc/grub.d/00_header  caused the problem.
       if terminal_output gfxterm ; then true ; else

so grub does not support 'true' as in bash.
