Having 'format.outputDirectory' is convenient, but being able to process all produced patches via a wildcard command is even more so. I.e., using an argument like '<dir>/*'. Neither '-o' nor 'format.outputDirectory' can be parameterized to produce a new unique directory. Thus provide the new 'format.outputDirectoryCmd' configuration to specify a command which does the job and puts the name to standard output.
