In lines 2425-2435 of cmdline/apt-get.cc I see:

         ioprintf(c1out, _("NOTICE: '%s' packaging is maintained in "
                           "the '%s' version control system at:\n"
                           "%s\n"),
                  Src.c_str(), vcs.c_str(), uri.c_str());
         if(vcs == "Bzr")
            ioprintf(c1out,_("Please use:\n"
                             "bzr branch %s\n"
                             "to retrieve the latest (possibly unreleased) "
                             "updates to the package.\n"),
                     uri.c_str());
         break;

So when running "apt-get source SOMEPACKAGE" I am sometimes warned to
use "bzr branch" instead.

Sometimes I am warned to use "git clone" or "svn checkout", but I can't
find the code for this in the apt package; maybe it is located
elsewhere?

At any rate, I was recently advised that for packages stored in git
repositories, I should (sometimes) use "git-buildpackage" instead of
"debuild binary" or "dpkg-buildpackage" to build from source.

At the risk of making Ubuntu dangerously user-friendly, I suggest that
the same code that warns to check out from a repository should also
advise that non-standard build tools may be needed, or at least point to
a documentation page somewhere that lists the various possibilities.
