Some other fixes not associated with reported bugs:

    The gnc_gui_refresh_all statement in gnc_book_options_dialog_apply_cb causes \ 
the 'apply' and 'OK' buttons to be set to sensitive on the open Book Options \ 
dialog in some circumstances; this commit causes them to be reset to \ 
insensitive, as they should be.
    Check printing: make logic easier to follow.
    Fix adjust_sql_option_string test on Windows.
    Don't try to compile test_adjust_sql_options on windows, it won't link.
    Fix the CMake build by linking gnc-backend-dbi for test-backend-dbi.
    Improved adjust_sql_options_string, added tests.
    Improve quickfill performance on huge registers.
    Mac Localization: Prefer the country to the language for fall-back locales, \ 
on the theory that in countries where multiple languages are in use similar date \ 
and number formats will apply regardless of language, and especially that the \ 
default currency will be the same regardless of language. Also ensure that the \ 
specified language is in the list passed to gettext; the net effect of which is \ 
that the user will effectively get the requested localization behavior.
    Update README to refer to wiki Submitting_Patches and regarding pull request \ 
policy.
