54
5504/25
56- after comparing, popup the changelist for the user
57- moved the relevant code from compare_to_cds() into
58 compare_mode(), so that tape users may benefit too
59
6004/24
61- added lots of assert()'s and log_OS_error()'s
62- cleaned up a few uninitialized strings (valgrind)

84- write log_to_screen()'s string to stdout if in text mode
85- update_progress_form_FULL(), update_evalcall_form(),
86 popup_and_*(), ask_me_yes_or_no() now write
87 XMondo-friendly info to stdout if in text mode
88- if fatal error then popup and say what the fatal error is
89- run_program_and_log_output() now takes boolean operator to specify
90 whether it will log its activities in the event of _success_
91- added popup_changelist_from_file(char*source_file, char*topic, void*call_if_entry_selected(void*));
92
