Applications can use various mechanisms to specify the characters that
should break words for the readline word completer.  It's an application-
specific setting, since different applications have different syntax.  Bash
happens to use the COMP_WORDBREAKS variable, which is reflected as the
value of readline's rl_completer_word_break_characters variable.
