src/calendar.c: Fix range check in calendar_move()
We added count prefix support to motion commands in commit 59e006e56d9f893506af56a4ca114fe53b537e49 but obviously forgot to check whether the range checks in calendar_move() still work correctly. Refactor out range checks and replace them by a single check that is performed *after* the new date is computed, but before we assign the new value to the actual selected date. This ensures we won't have to bother about these again when changing/adding functionality in/to calendar_move(), while keeping performance (date_change() is pretty cheap and range violations are corner cases anyway).
