[ Upstream commit 2351e8c65404aabc433300b6bf90c7a37e8bbc4d ]
Some distros have grub2 config files with the lines
if [ x"${feature_menuentry_id}" = xy ]; then menuentry_id_option="--id" else menuentry_id_option="" fi
which match the skip regex defined for grub2 in get_grub_index():
$skip = '^\s*menuentry';
These false positives cause the grub number to be higher than it should be, and the wrong kernel can end up booting.
Grub documents the menuentry command with whitespace between it and the title, so make the skip regex reflect this.
