The syntax can be changed without too much effort. I wonder if
supporting a set of reminders (warning times) is a welcomed feature.

I am thinking something like this.

The last element in appt-time-msg-list, the warning time, can take a
list of times and for each but the last value in that list, it will warn
for a duration (say 15 minutes).

For my personal use single warning time is enough. My patch is to
address the issue that setting a good default value for
appt-message-warning-time is impossible.
