I have cause to add a customisation to my grub.cfg file, so I've been reading
the GRUB manual.

I noticed that the string equality test syntax, under the "test" command
section, is documented as double equals sign (==).

But in all my encounters of grub.cfg, including generated ones for years and
years now, I've only ever see a single equals sign (=). ie:


        if [ "${1}" = "keep" ]; then


Admittedly, I have not tested if the double equals works in the same way, but
even if it did (so it's an either/or proposition), shouldn't the single equals
be documented as well?
