line with the output of "date". This is useful to add a timestamp to a file.
+Note: There is a difference between "!cmd" (e.g. using it without any file
+range) and "{range}!cmd". While the former will simply execute the external
+command and Vim will show the output, the latter will filter {range}lines
+through the filter and replace that range by the result of the filter command.
