libapt has the pkgAcqChangelog class which can be used for this, e.g.

new pkgAcqChangelog(&Fetcher, Ver, ".");

to download the changelog file to the current directory – without giving
a path it will us a temporary file. See apt-private/private-download.cc
and especially DoChangelog for the implementation of "apt(-get)
changelog" as a complete example.

Perhaps this is another command aptitude could delegate entirely by
calling apt – but I don't know aptitude specifics.
