} Wow. filenames shouldn't listed.

It's only directory names, and it's related to:

} is27e1u11% cvs --allow-root=CVS/
} 
} Of cause, the option `--allow-root' shouldn't completed.

If you do
    compstyle '*:descriptions' format '%d'
before trying "cvs <TAB>", you'll see that it says

cvs command
rootdir

So it's listing directories to be the argument of --allow-root=.  This
in turn is because _arguments at line 299 is calling

	compadd -M  -D equal - --allow_root

and then setting IPREFIX to --allow-root= at line 304, etc.  However,
it's beyond my understanding of the interaction between _arguments and
comparguments to tell how it got into that state in the first place.
