Bug#545740: grep -c without needing to then pipe sed '/:0$/d'

[jidanni]

X-debbugs-cc: address@hidden
Package: grep
Version: 2.5.4-4
Severity: wishlist

Regarding
  -c, --count               print only a count of matching lines per FILE

$ echo zzz>ddd
Why can't there be a way to get rid of
$ grep -c zzz *|wc -l #these 30 extra lines:
31
$ grep -c zzz *|sed '/:0$/d' #<-- without having to resort to this
ddd:1

Wouldn't adding an optional way to specify "don't tell me about files
with no matches" be more in the grep spirit?
