jit-lock seems to require lots of extra work compared to adapting
prettify-symbols-mode and asking the user to add extra settings.
jit-lock is not tied to regexp lookups, which is OK with me (a scanning
function is better for my specific need, since secrets are often
contextual).

The cleanest example I saw was glasses.el but that mode doesn't reveal
the transformed text when you're inside the text.

Is there an example using jit-lock that behaves like
prettify-symbols-mode in the following cases?

* transforms the text when outside it
* temporarily shows the original text when inside it or on its right edge
* updates when the user makes changes

Thank you again
Ted
