Ok but anyway, shouldn't this be mentioned in the manual? It's pretty much intuitive that if space is removed (which is the first one easily noticed), so should other separators specified in COMP_WORDBREAKS. In my opinion it would have been better if separators were stored in another variable than COMP_WORDS instead, where the index is the index in COMP_WORDS of the word that follows the separator or sequence of separators minus one. -- konsolebox
