Patched bytes have relocation information

If a byte has relocation information attached to it, then the value of this byte is changed when the file is loaded into the memory by the system loader or linker. Therefore it doesn't make much sense (and sometimes it is simply illegal) to modify the byte.

The recommendation: return the original value of the byte(s).

You can see the relocation information attached to an item by using the show internal flags command.
