Thanks.

I found the argument name 'fseek' confusing here, since this mimics a
global function of the same name.  Could you rename the argument?

Newline after 'void'.

I wonder whether the null fseek ought to unconditionally throw an
exception.  It seems to me that it can't really be successful.

I think this should go in conditionally based on the other patches -- no
need to put it in if it turns out you can't use ui_file after all for
some reason.
