Cygwin's regex implements POSIX regular expressions as described in,
for instance,
http://www.opengroup.org/onlinepubs/009695399/basedefs/xbd_chap09.html

What you're looking for are perl regular expressions and they are
only available if nano is built against the perl regex library which
apparently it isn't.
