When a kernel command-line option contains an embedded space such as this example from /boot/grub/grub.cfg:
linux /vmlinuz-4.13.0-19-lowlatency root=/dev/mapper/VG_OS-ubuntu_16.04_rootfs ro nopat pci=use_crs,realloc,assign-busses,pcie_scan_all acpi_osi=! "acpi_osi=Windows 2006" splash $vt_handoff
The result from calling linux-boot-prober is passed through 'tr' which replaces all spaces with ^ to mark fields:
LINUXPROBED="`linux-boot-prober btrfs ${BTRFSuuid} ${BTRFSsubvol} 2> /dev/null | tr ' ' '^' | paste -s -d ' '`"

When a kernel command-line option contains an embedded space such as this example from /boot/grub/grub.cfg:
linux /vmlinuz-4.13.0-19-lowlatency root=/dev/mapper/VG_OS-ubuntu_16.04_rootfs ro nopat pci=use_crs,realloc,assign-busses,pcie_scan_all acpi_osi=! "acpi_osi=Windows 2006" splash $vt_handoff
The result from calling linux-boot-prober is multiple entries with the name of the embedded-space parameter:

With multiple Linux OS installs on a single block device additional false menuentry's for the 'foreign' OS built by linux-boot-prober are generated when there are double-quoted kernel command-line options present.
When a kernel command-line option contains an embedded space such as this example from /boot/grub/grub.cfg:
linux /vmlinuz-4.13.0-19-lowlatency root=/dev/mapper/VG_OS-ubuntu_16.04_rootfs ro nopat pci=use_crs,realloc,assign-busses,pcie_scan_all acpi_osi=! "acpi_osi=Windows 2006" splash $vt_handoff
