/*
* Handle all the more complicated user interactions with an entry list menu.
* Whenever the user begins editing a row, the entry in that row is copied
* to the edit struct. All editing takes place, until it is confirmed and
* put back into the main list. The reason for this is that entering a new
* date or time doesn't make the row disappear from the current list because
* it now belongs to a different day before editing is finished.
*
* got_entry_press(w,lw,x,y,on,b) The user pressed on one of the
* buttons in the list menu button array.
* confirm_new_entry() Puts the currently edited row back
* into the mainlist, and re-sorts.
* undo_new_entry() Kill the edit buffer, undoing the
* changes to the current row.
* got_entry_text(lw, x, y, text) The user entered text into the text
* button. There is never more than one.
* sensitize_edit_buttons() Desensitize all buttons in the
* bottom button row that don't make
* sense at the moment.
