This may be one of those cases where an option is undocumented because
it doesn't work.  Note that the V7 manual page says "(grep only)" for the
-y option, i.e. it claims that fgrep doesn't take -y.

(For anyone mystified by this discussion:  -y is the "dualcase" option
that makes lowercase pattern letters match either lowercase or uppercase
data letters.)
