that is not the real problem, svn also doesnt allow you to remove revissions
without hacking the repo

what i would like (i of course dont know if that matches what nico wants)
is that i can take revision X of file Y and copy that to a new file or
replace the head version of the old file by it, and that
annotate/log will show the true history that is without the revissions
which are not part of that branch or alternatively clearly seperate the
revissions which arent part of the file

ive tried a mix of hg up <oldrev> and hg cp+ci but it doesnt seem to work
hg up isnt supported at that point and hg merge will f*ck up the copied
file

if there is no way to branch past revissions properly then mercurial is out
of question for me for ffmpeg
but i hope that iam just too stupid to use mercurial, after all with that
limitation we couldnt even branch a release off in the same repository
but rather would have to create anew repository for that which is idiotic
