As it turns out, the problem is the way `="' is split.  If you want to
treat quoted strings the way readline does, you can't use `'' or `"' as
a word delimiter when splitting the line, regardless of whether or not
they're in rl_completer_word_break_chars ($COMP_WORDBREAKS).

I'll have a fix in the next devel branch push.
