I ported it to bourne shell. It's tested and known to work with dash as
/bin/sh. I think this should address your concern.
My new patch also arranges the logic for generating update-grub components
to make it more similar to how grub-install is handled.

+All executable files in this directory are processed in shell expansion order.
+
+ 00_*: Reserved for 00_header.
+ 10_*: Native boot entries.
+ 20_*: Third party apps (e.g. memtest86+).
+
+The number namespace in-between is configurable by system installer and/or
+administrator. For example, you can add an entry to boot another OS as
+01_otheros, 11_otheros, etc, depending on the position you want it to occupy in
+the menu; and then adjust the default setting via /etc/default/grub.
