Hi,
How do I compare a customized variable value with its original value?
When I `describe-variable' I get "value" and "original value", sometimes
it's hard to see the difference. Is there a quick way to diff them?

I think you are looking for “sexp diff”. I recall seeing one on [search engine], but it wasn’t feature complete. Maybe you will have better luck this time.
For completeness, here’s how you access the standard value programmatically:
(customize--standard-value 'var-name)
Or take a look at the implementation of this function: it’s just `eval'’ing the sexp of one of the symbol’s properties.
