No big deal but the *.sgml files belong into the en/ subdirectory.
IMHO it would be no real harm to work in master. As long as you not say
`make publish` the doc is not updated online and chances that people dig
into Vcs to get the latest doc is converging to zero. (If only people
would read the online docs I'd be more than happy. ;-))
I think it would be a useful task to download *every* Blends Vcs and
recreate the needed files and also *commit* the resulting files back to
SVN, specifically to circumvent the changelog problems. So once we
might switch to blends-dev 0.7 all Vcs are prepared. The only Blend you
should not commit anything to is Debian Edu because they are preparing
a Wheezy release and do not want to change anything. But I think you
would need to be a member of debian-edu group anyway to commit to this
repository.
