I agree.

I think an improved approach would be one of those:

1) Make gencmdlist.sh call cpp with a special macro, that would expand
into something that can be reliably extracted by sed or grep and placed
into command.lst.

2) Use a macro to write the symbol into a special linker section.
gencmdlist.sh would read it to generate command.lst at the build time.

3) Use a macro to write the symbol into a special linker section.
grub-install would run a new utility to generate command.lst from the
modules in /boot/grub.

The later is very appealing, but it would be a big change in the way we
are doing things.
