Autocomplete activates on lines beginning with variable names

[doimus]

The current implementation of autocomplete activates on lines beginning with variable names, when SPACE is pressed. For example:

DIM x AS UBYTE works as intended.
LET x = 1 works as intended.

But when trying to type:
x = 1
the autocomplete will activate after pressing space and the line will appear as:
XOR = 1
since XOR is the default autocomplete option in this case.
This behavior introduces lots of unnecessary bugs and works against muscle memory from other IDEs.
