Predicates consisting of [.-:=]+ charaters not supported.

Good work, only found that predicates consisting of [.-:=] characters can break the syntax a bit.

:- op( 220, xfy, .. ).
:- op( 220, xfy, .==. ).
:- A = a..b.

Wow, this is a year old. I guess I missed it in my feed :-\

Anyway, I haven't been maintaining this for a while, since I don't really do any Prolog code right now, but I'll try to look into a fix soon.

hehe, I also completely forgot about it. Just that once in a while I have to assist a Prolog course, I think I just added the used operators explicitly to the syntax. Cheers!
