It's not possible to make a single commit which would affect both files.
I haven't set up repositories to test what the commandline tool does if
you give it paths from different repositories (it might make independent
commits to them using the same comment, or it might just fail). At least
"svn commit" will not commit anything under externals.

I mean the global repository history (as shown by "svn log -v" at the
top level), that's more than just a change in revision numbers.

Yes, it's comparable to MPlayer and lavc/lavf, but I think it is a real
problem with MPlayer too so it shouldn't be ignored here just because it
already happens somewhere else.

If you don't agree with what I consider to be the most practical
solution but don't want to discuss your requirements further then I
think trying to come up with alternative proposals based on just
"distort the history as little as possible" would be a waste of my time.
I don't see keeping the previous history only in the repository where it
happened (and where it's readily accessible) as "distorting" it myself.
