Does that really correspond to the previous behavior?
...
(when (eq 0 status)
(if (string-match "changeset: *\\([0-9]*\\)" out)
(match-string 1 out)
"0"))))
It returns "0" when there is no match but nil if status doesn't equal 0:
when is a Lisp macro in `subr.el'.
(when COND BODY...)
If COND yields non-nil, do BODY, else return nil.
Also, iget a quoted string, e.g. "\"290\"", which is why I used read.
