util/grub-mkconfig_lib.in(version_test_gt): "echo -n" is not really needed, final newline is stripped by command substitution. util/grub.d/10_kfreebsd.in, util/grub.d/10_linux.in, util/grub.d/20_linux_xen.in: change how list is built, to avoid echo -n completely. util/grub.d/30_os-prober.in: add spaces to printed line directly Closes 43668.
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.
