Yes: I said that considering the situation, it might be best to throw
away the existing history, and add the code in a single commit.

Sure, it would be nice if the various changes that happened in the past
were reflected in the history -- but this would be a lot of work; and I
don't think it's really worth the effort in this case. The code is still
rather experimental; and AFAIK nobody ever tested it but yourself. All
in all, it doesn't seem very likely that we will ever want to track
regressions in the old commits...

Yes, you should definitely clean it up. This can probably happen after
the merge -- especially if you also clean up the code itself, not only
comments: in this case, it might indeed become necessary to track
regressions in the cleanups :-)

One patch for each type of cleanup I'd say.

I've never done this myself, so I actually don't know for sure. I
believe that it should be possible to simply do a normal merge. The
tricky part is that after the merge the stuff needs to be in a
subdirectory, while in the original repository it was top-level; so
first it's necessary to move the code. Making the move part of the merge
commit itself (rather than an extra commit before the merge) might
require some magic...

But if we drop the old history, we don't need any of that. Just copy the
whole directory (dropping the original .git/ ), add it to the index, and
commit, with something like "initial import of nsmux" as commit message.

Of course, you also need to adapt the build system somewhere along the
