Oh.  *That* second '\0'.  Duh.

I was under the impression that it was legal to terminate the final
entry in /etc/group with a colon but testing on linux shows that it
isn't.

I'll change this to strchr.  Actually, I'll change it to 'strechr' since
implementing strechr is another thing I've been meaning to do for a
while.  strechr is a variation of strchr which returns EOS on failure.
It could simplify code throughout cygwin.
