retrieving stored data (for the --menu, --calendar, --timebox, --checklist, and --radiolist widgets). When we (Ron McDowell and I) developed the first version of bsdconfig, it used temporary files to store responses from dialog(1). That hasn't been true for some very long time, so the need to always store the return status of dialog(1) and then call some function to clean-up is long-deprecated. The function that used to do the clean-up was f_dialog_menutag(). We really don't need f_dialog_menutag() for its originally designed purpose, as all dialog invocations (even when in a sub-shell) do not use temporary files anymore. However, we do need to keep f_dialog_menutag() around because it still fills the need of being able to abstract the procedure for fetching stored data provided by functions that display the aforementioned widgets. In re-designing f_dialog_menutag(), four important changes are made: 1. Rename f_dialog_menutag() to f_dialog_menutag_fetch() 2. Introduce the new first-argument of $var_to_set to reduce number of forks 3. Create a corresponding f_dialog_menutag_store() to abstract the storage 4. Offload the sanitization to a new function, f_dialog_data_sanitize() NOTE: That last one is important. Not all functions need to store their data for later fetching, meanwhile every invocation of dialog should be sanitized (as we learned early-on in the i18n-effort -- underlying libraries will spit warnings to stderr for bad values of $LANG and since dialog outputs its responses to stderr, we need to sanitize every response of these warnings). These changes greatly improve readbaility and also improve performance by reducing unnecessary forking.
