Bug#872637: grub-pc: reconfigure includes options from /etc/default/grub.d/*.cfg in /etc/default/grub

[Paul Wise]

Package: grub-pc
Version: 2.02-2
Severity: normal

I migrated my custom Linux kernel command-line options in the 
GRUB_CMDLINE_LINUX variable in /etc/default/grub to files in
/etc/default/grub.d/*.cfg that add new options to GRUB_CMDLINE_LINUX
like the line below. When I `dpkg-reconfigure grub-pc`, the prompt for
Linux kernel command-line options includes foo.bar=baz and then
immediately triggers a ucf conffile update prompt, with the diff being
the addition of the options I set in the grub.d files.

GRUB_CMDLINE_LINUX="$GRUB_CMDLINE_LINUX foo.bar=baz"

I think it would be better for the prompts to not include options from
grub.d so that the main grub default file doesn't get updated and the
ucf prompt does not appear.
