But things like escape (^[) don't get ignored. I've noticed my bad
habit from vi causes "invisible escapes" to be embedded within files
I'm editing in ProjectCenter. And consequent compile-phase failures.
I haven't checked a recent version of CodeEditor. Is its behaviour
better (if only showing "box" glyphs or something)?
