Reclaim Esc for default TM completion.

COGODE completion is now triggered on Opt-Esc.
Fixed: variable init scoping (var...)

Previously all space and commas were matched into a variable
scope, which caused problems with word selection.

Similar to previous fix for variable initialisation using ":=".
Remove invalid "->" channel operator.

Rename scope to highlighted "<-" as operator.
