mount(8) merely says,

        "Various misguided attempts to force Unix or DOS conventions
        onto a FAT file system."

'showexec' is not listed in the kernel documentation either. However,
'include/linux/msdos_fs.h' reveals its purpose:

        struct fat_mount_options {
                ...
                showexec:1,      /* set = only set x bit for com/exe/bat */
                ...
        };

So I guess this is safe.
