1) Why does apt-get source fetch a different source package to the one named
in the arg?
Because the name of the source package is usually not the name of the binary
package. And one source package could result in many binary packages. For
example, when searching for packages on http://packages.trisquel.info/ this
is why you have the option to search for "source package names."
Or why, when viewing a binary package, there is a link to the (differently
named) source package. For example: Notice how
http://packages.trisquel.info/belenos/emacs has a link called: [ Source:
emacs-defaults ] in the upper left.
So when you use apt-get source you should be plugging in the name of the
source package but it seems smart enough to figure out the proper thing when
you don't. :)
