VC: log of sub-directory?

[Óscar Fuentes]

VC-dir only shows modified files, so if the user wants to see the log of
an unedited file he must to visit it and then C-x v l

But AFAIK, there is no way of seeing the log of a versioned
sub-directory. I'm not sure how that could be implemented (maybe C-x d
<directory> [INTRO] C-x v l)

If VC-dir were allowed to optionally show unmodified elements (files,
directories) as psvn does (and PCL-CVS IIRC) it could be somewhat
convenient. Seeing the combined log of two or more files is not possible
either. Being able to mark unedited files on the VC-dir buffer could
solve that too.
