Thank you for the patch.

"*" comes after the space.

If a data structure holds an address that already has the section offset
applied, then objfile_relocate1 must be updated to relocate the value.

However, if you can possibly avoid adding the section offset, in favor
of handling this when the address is used, then that is better IMO.

thanks,
Tom
