[Remind-Fans] A way to find expired alarms?

[Mayuresh]

Is there any way to find out expired reminders - those that will never
trigger in future?  One may like to either go and delete them or set next
date on them etc.

An outside-remind (shell script etc) way is also ok.

A crude way I could think of is to pass every single reminder separately
to remind with -t option and see whether it triggers. But that's a little
painful. Any easier way out?
