Hello Jim,
Sorry for the delay. ;-)

Hehe. I see a chance to reconcile some stuff I've been solving locally
or doing inefficiently.

No, it did not have any changes. I was somehow under the impression
that this would help me generate a ChangeLog entry for other files that
I changed; upon second reading that seems not to be intended at all,
so I guess the program worked as intended, just the message was a bit
confusing. Maybe just not output anything at all in that case?
While we're at this: how about if vc-dwim helped me generate a stub
ChangeLog entry (with file names listed, maybe functions)? I don't know
how others do this, but I think you don't want to know how I do it.[1]
And going even further, there are some projects that use some of the
newer version control systems but do not store their commit logs in a
ChangeLog; for example, with svn I've grown accustomed to tracking my
personal ChangeLog file with a script like the one very imperfect one
below[2]. Maybe vc-dwim could do something like this for me in a
vcs-agnostic manner? ;-)
I haven't tested it with genuine changes yet.
FWIW, it would be really nice to see the changes from 0.2.1 also in the
hg tree (I prefer a vcs-ed upstream when providing feedback).
Cheers,
Ralf
[1] Note I seem unable to teach my fingers the emacs way of life, and
AFAIK vim does not have a generate-changelog-stub kind of function;
maybe I should write one ... but also I only know of emacs functions
that do so based on version control commits; too late for GNU projects.
