/* The search settings between the dialog's widgets (checkbuttons and the text
 * entry) and the SearchSettings object are not bound. Instead, this function is
 * called to set the search settings from the widgets to the SearchSettings
 * object.
 *
 * The reason: the search and replace dialog is not an incremental search. You
 * have to press the buttons to have an effect. The SearchContext is created
 * only when a button is pressed, not before. If the SearchContext was created
 * directly when the dialog window is shown, or when the document tab is
 * switched, there would be a problem. When we switch betweeen tabs to find on
 * which tab(s) we want to do the search, we may have older searches (still
 * highlighted) that we don't want to lose, and we don't want the new search to
 * appear on each tab that we open. Only when we press a button. So when the
 * SearchContext is not already created, this is not an incremental search. Once
 * the SearchContext is created, it's better to be consistent, and therefore we
 * don't want the incremental search: we have to always press a button to
 * execute the search.
 *
 * Likewise, each created SearchContext (from the GeditReplaceDialog) contains a
 * different SearchSettings. When set_search_settings() is called for one
 * document tab (and thus one SearchSettings), it doesn't have an effect on the
 * other tabs. But the dialog widgets don't change.
