I can confirm this at both xemacs21 21.4.17-1(sarge) and
xemacs21 21.4.18-3(sid). But, this doesn't occur at emacs21.
I'll investigate this more.
---- xemacs21
(string-match "\\(-[a-z]+\\)\\{1\\}" "-ab-cd")
0
(string-match "\\(-[a-z]+\\)\\{2\\}" "-ab-cd")
0
(string-match "\\(-[a-z]+\\)\\{3\\}" "-ab-cd")
0
(string-match "\\(-[a-z]+\\)\\{4\\}" "-ab-cd")
0
(string-match "\\(-[a-z]+\\)\\{5\\}" "-ab-cd")
nil

---- emacs21

(string-match "\\(-[a-z]+\\)\\{2\\}" "-ab-cd")

(string-match "\\(-[a-z]+\\)\\{3\\}" "-ab-cd")
nil
(string-match "\\(-[a-z]+\\)\\{4\\}" "-ab-cd")
nil
(string-match "\\(-[a-z]+\\)\\{5\\}" "-ab-cd")
nil
