Actually enhanced __get_cword3 to _get_cword, and removed __get_cword4. __get_cword4 could handle chars to exclude from COMP_WORDBREAKS, but failed with partial quoted arguments (e.g. "a 'b c|", | = cursor position). This was no problem till bash-4.0.35, because bash < 4.0.35 also returned partial quoted arguments incorrectly. See also: http://www.mail-archive.com/bug-bash@gnu.org/msg06094.html Now that bash-4.0.35 returns quoted arguments ok, __get_cword3 is enhanced to also handle chars to exclude from COMP_WORDBREAKS. Because __get_cword3 also handles partial quoted arguments correctly, this makes __get_cword3 suitable for bash-4 as well.
