No, the bug is that while 'gzip' and 'grep' are C programs, 'zgrep' is a
shell script, and the option parsing within that shell script has not
yet been tweaked to correctly parse options in the same way that 'grep'
would. You have found a valid bug, and hopefully someone will take the
time to revisit the shell script parser in zgrep (I unfortunately
couldn't unravel it in the 2 minutes that I spent on the problem, and
currently have more pressing matters competing for my attention, so
hopefully someone else can step in and help).
