Re: _history-complete-older problems with $(

I have one idea. It's generally about detecting a syntax error that
makes shell word unbound. By appending " x" to shell word and running
(Z+n+) one can obtain either 1 or 2 elements and first signals a
syntax error. For such case, SUFFIX would consist only from a space
delimited part of the regular right part.

Best regards,
