[Cuis-dev] Parser gets confused when using $| in binary selectors

[Juan Vuletich]

Updated version is attached.

Hilaire, please check that the use of Preference NG is reasonable.

Folks, please check that the names and default I used make sense.

Let's hope that whoever modifies that preference knows what they are doing.
For example for loading code for Pharo. In that case, the default 
behavior will break stuff.
Shortly, I'll try all packages in the Cuis-Smalltalk github organization 
with the preference at #disabled, to find and fix existing code that 
would break in such case.

Besides, I suggest having it at #disabled when writing code, to avoid 
unneeded suffering in the future.

Thanks,
