While at it: Multiple values should be separated by a space character, not by a semicolon. Apart from that, it would be nice if it would also print the `warn` and/or `crit` fields (when the user specified thresholds on the command line). Maybe also `min=0`, at least for the file size (I guess the age might be negative if the file's `mtime` is in the future?). See the [Development Guidelines][1] for the expected format.
