+# diffstat

+Show diff statistics.

+
+maybe not 100% correct, but it's one case where being simple yet
+slightly wrong is way easier than correct.  It's not a catastrophe to
+count some extra lines, while parsing the diff (possibly enclosed in a
+mail) is hard.
+
+	/^\+/ { a++ }
+	/^\-/ { m++ }
+
+Don't be a sink!  Continue the pipeline so we can further save or apply
+the diff.
+
+	// { print $0 }
+
+At the end, print the stats to standard error to avoid mangling the
+input.  Unfortunately, there doesn't seem to be a "built-in" way of
+printing to stderr other than using the pseudo-device.
+
+	END {
+		print "+", a > "/dev/stderr"
+		print "-", m  > "/dev/stderr"
+	}
+
+some example usages:
+
+* cvs -q di | diffstat | tee /tmp/diff | less
+* git diff | diffstat > /tmp/diff
+* got di | diffstat | ssh foo 'cd xyz && got patch'
