This is great, I've was eventually going to get to this. Although I'm
not the maintainer, I have a few comments,

You should probably be using symtab_to_fullname instead of
source_full_path_of. In fact, maybe source_full_path_of should be
deprecated. symtab_to_fullname is used in mi/mi-cmd-file.c.

Also, there should be a corresponding testcase, that ensures the new 
field is working properly.

Thanks,
