event expansion vs. tab expansion

[Ingo60]

It looks like the jline repl does "event expansion":

frege> !true
[ERROR] Could not expand event
java.lang.IllegalArgumentException: !true: event not found
at jline.console.ConsoleReader.expandEvents(ConsoleReader.java:849)
at jline.console.ConsoleReader.finishBuffer(ConsoleReader.java:700)
at jline.console.ConsoleReader.accept(ConsoleReader.java:2010)
at jline.console.ConsoleReader.readLine(ConsoleReader.java:2691)
at jline.console.ConsoleReader.readLine(ConsoleReader.java:2372)
at jline.console.ConsoleReader.readLine(ConsoleReader.java:2360)
    ....

This is unfortunate, as we have to escape every occurence of ! with a backslash.
Is it possible to turn this off?

On a related note, what would be great to have would be tab expansion.
I am sure there are some predefined tab-handlers that take a list of items or some such, and that list could easily be constructed from the base names of all known symbols, plus the known module names.

I have disabled event expansion so ! should work now. I have updated the snapshot release with this fix.

Regarding tab expansion, jline does support the concept of completers so it should be possible to define one for Frege symbols. I will dig into this.
