The most often used operation is to commit edited files.

Maybe to make it easier to e.g. register all unregistered files:
in VC-Dir type 'm' on an unregistered file that will mark all
unregistered files, then register them with 'v'.

Then typing 'v' in Dired should open the *vc-log* buffer
for writing a commit message on all edited files,
ignoring all unregistered files?

>> BTW, why 'C-x v d RET' requires a confirmation?
>> This additional 'RET' is too annoying.

I remember bug#12492, but not any other discussion.
