Thanks for the report and diagnosis.
While changing the zgrep script does indeed solve
your problem, you should consider adjusting your
shell's search patch instead.

If you put /opt/csw/bin in "PATH" before /bin and /usr/bin,
that will solve the problem, too.  It has the added benefit
of making your use of "grep" on the command line select the
more featureful version.

There are pros and cons of hard-coding an absolute path to grep in a
script like zgrep.  Currently, it seems preferable *not* to hard-code it,
and instead to let the user's PATH select which one to use.
