I don't think the man page is saying anything about the order of the --source
option relative to the --changes option.

I see two mentions of the order being relevant. Once for the --source option:

 | The ordering is significant: each --source option should precede options
 | whose dependencies are to be satisfied by the binaries it produces.

And once for the --binary option

 | The ordering is significant, as for --source. In particular, if a subsequent
 | source package will build a binary of the same name, that will be used from
 | then on, and deb will be ignored.

And I read both before filing this bug but was unable to see how any of these
applies to the order of options when combining --source with --changes.

So at least this bug should be kept open until the following very valuable hint
is documented:

> I. e. use "adt-run pkg_*.changes -B pkg_*.dsc" for your use case.

In fact, from the existing docs I interpreted that the --source option must
come after the --changes option as it says that if there source packages
building binary packages of the same name, then they will *overwrite* these
binary packages which is not what I wanted so I thought that the --changes
option should come *after* the --source option.

So I think this should be clarified in the man page.
