Re: [RFC PATCH 3/3] format-patch: use a command to generate the output directory name

Bert Wesarg [off-list ref] writes:

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.

The above does not interest me (a reader) enough, without the log
message explaining why

	git format-patch -o "$(outdircmd)"

is not sufficient.

Thanks.
