[syslinux] Usage output of Syslinux installers is not consequent

[Gert Hulselmans]

Why doesn't the Windows Syslinux installer show:
--offset and --directory too (I know it is not supported)?

Because the Linux versions show the Windows/dos specific commands:
--mbr --active and --force

I didn't check the DOS version.

If all options will be displayed unconditionally for all installers, it
might be a good idea to add:
  --offset     -t  Offset of the file system on the device (mtools installer)
  --directory  -d  Directory for installation target (mtools installer)

$ wine ./syslinux-git/working-directory/win32/syslinux
Usage: Z:\home\gert\syslinux-git\working-directory\win32\syslinux.exe
[options] <drive>: [bootsecfile]
  --install    -i  Install over the current bootsector
  --update     -U  Update a previous EXTLINUX installation
  --zip        -z  Force zipdrive geometry (-H 64 -S 32)
  --sectors=#  -S  Force the number of sectors per track
  --heads=#    -H  Force number of heads
  --stupid     -s  Slow, safe and stupid mode
  --raid       -r  Fall back to the next device on boot failure
  --once=...   -o  Execute a command once upon boot
  --clear-once -O  Clear the boot-once command
  --reset-adv      Reset auxilliary data
  --menu-save= -M  Set the label to select as default on the next boot
  --mbr        -m  Install an MBR (DOS/Win32 installers only)
  --active     -a  Mark partition as active (DOS/Win32 installers only)
  --force      -f  Ignore precautions (DOS/Win32/mtools installers only)

  Note: geometry is determined at boot time for devices which
  are considered hard disks by the BIOS.  Unfortunately, this is
  not possible for devices which are considered floppy disks,
  which includes zipdisks and LS-120 superfloppies.

  The -z option is useful for USB devices which are considered
  hard disks by some BIOSes and zipdrives by other BIOSes.
