That would work too, but abbreviating commits is not always correct...

How about using `format-spec' together with a user option to format the
success messages?  E.g. you could set it do "Source package `%n'
installed (Version %v, Revision %6r)".

Then again, I don't know if this issue is that important.

VC doesn't expose a convenient way of fetching commit messages from revisions.
