Boy they really blew it when they invented -c,
   (info "(grep) General Output Control")

  =E2=80=98-c=E2=80=99
  =E2=80=98--count=E2=80=99
       Suppress normal output; instead print a count of matching lines fo=
r
       each input file.  With the =E2=80=98-v=E2=80=99 (=E2=80=98--invert=
-match=E2=80=99) option, count
       non-matching lines.  (=E2=80=98-c=E2=80=99 is specified by POSIX.)

Who in the world ever wants to know about the zero match counts (:0)? ;-)
OK, well then add some extra switch for the rest of us... or at least the=
 INFO
page should mention how the pros filter them out.

#1
time find * -name \*.html | xargs grep -l staticmap | xargs grep -c stati=
cmap | head -n 3
location/directions/zaokeng.html:1
location/yaokeng_road.html:1
location/yaokeng_road2.html:1

real	0m0.015s
user	0m0.013s
sys	0m0.002s

#2
time find * -name \*.html | xargs grep -c staticmap | grep -v :0$   | hea=
d -n 3
comm/air/m750/trail.html:1
comm/air/m750/index.html:1
geo/house_numbering/taizhong/dongshi/index.html:1

real	0m0.017s
user	0m0.011s
sys	0m0.004s

(#1 is a big waste, but the real time is randomly a little shorter, as
it takes larger inputs so really see the difference.)

Anyway I've never ever wanted the :0s.

Wait! Maybe "-cl" or "-lc" will give us what we want!
Alas, they are just equivalent to "-l".
(As I suppose that fact is not documented, perhaps it could be given a
new (non-backwardly compatible, alas) definition...)
