I am having strange behaviour when tabbing before a ‘-’ char:

$query [CURSOR BEFORE TAB]->entityCondition('entity_type', 'node', '=');

Wrongly fireing autocomplete,
Expected tab indentation

results in :

$query set-screen-option>entityCondition('entity_type', 'node', '=');

I sugest a tweak to the autocomplete to not fire in this case.
