"patch_lba0=on" transfers within the data_to= file a copy of the currently
loaded session head to the start of that file and patches it to be valid
at that position.
This makes the loaded session the default session of the image file
when it gets mounted or loaded as stdio: drive. But it usually makes
the original session 1 inaccessible.

"patch_lba0=force" performs "patch_lba0=on" even if xorriso believes
that the copied data are not valid.

"patch_lba0=" may also bear a number. If it is 32 or higher it is taken as
start address of the session to be copied. In this case it is not necessary to
have an -indev and a loaded image. ":force" may be appended after the number.
