This should be possible to do with scripting, nonetheless I think that
having that numbers in the log would simplify things for the user.

Use case: suppose a user writes an application, since is using a
recently added functions she wants to setup its configure script so
that it will *require* to use a version not less than of the version
which added that feature.

Now she has to grok the log, possibly grepping for the function/field
which has been added, and when she detects the relevant revision she
can for example check the diff for that revision.

The problem is that it isn't always obvious from the log which is the
functionality added, and often even if a functionality has been added.

Having the updated library versions in the log would help in two ways: 
1) the user would spot immediately which are the changes which added
 functionality to the library
2) the user would find immediately in the log the version number, no
 need to perform other steps
