[Murray Cumming <murrayc src gnome org>]

commit 1284b29cf5806fdef2082dbaa885a6047398c693
Author: Murray Cumming <murrayc murrayc com>

    ListView: Make the rows high enough.
    
    * glom/mode_data/db_adddel/db_adddel.cc: get_fixed_cell_height():
    Add the GtkTreeView vertical-separator style property to the height,
    which might be the right thing to do, and which works here at least.
