The TagWidgets hook into the textChanged() signal to invoke the word-completer. However, that signal is also emitted for composition-keys, making composition impossible if the completer decides that it should show some entries. Instead, hook into the inputMethodEvent() function, where one can test whether a real character was input. Also, don't hook into cursorPositionChanged(), since that led to an uncanny cascade of reparse() calls when editing text. The UI experience is still rough as sometimes the completer popup steals the focus and hinders further entry. Also, this doesn't fix the location field, which is its own class.
