- Replace comparisons of software_entry() or part_entry() with nullptr with loaded_through_softlist() predicate. - Eliminate the superfluous m_software_info_ptr member. The software_entry() accessor is still provided, but now rarely used. - Eliminate two of the three arguments to load_software_part. - Remove some unnecessary auto-typing in ui/inifile.cpp.
