After updating to (probably) 4142, I get a tab-complete from pressing tab after many different single letters in the Plain Text syntax, even though I have tab completion disabled.
Can be easily reproduced by opening a new file, then typing the following (I use Plain Text syntax for assembly, and as one can imagine with some assembly languages, this gets tripped very easily if I want to add a comment!)
and L
where L can be replaced by any of the letters in “lorem”.
This is very frustrating, and I don’t have any idea what is causing it. I have a feeling that this probably shouldn’t occur even if I did have tab-completion on, but it certainly happens with it off at least.
