I wasn't worried about "entries with absolute paths".  I was worried about
relative_base that the caller passes may not be absolute but relative to
something (perhaps the processe's getcwd()); it seems that the call to
real_path() to turn it into an absolute one at the very beginning of the
link_alt_odb_entry() function does indeed take care of that case.

Thanks.
