I created a ticket for the "admin" submodule on GitHub.

I think there needs to be a global solution since many libraries are involved.

Yes, it seems some have been fixed since my first email.

Yes, I tried to clean up at least the boost directory in SVN. After all,
that's what you're supposed to install into the system.

I'd safely add *.cpp, Jamfile*, *.jam, *.qbk, *.jpg, *.gif, *.css, *.rst,
*.xml. Actually, it may be simpler to identify which files should be
executable than not: *.sh, *.py, *.pl, *.bat, *.cmd.

This should have been avoided by autoprops in SVN config that were supposed to
be set up by all developers. Obviously, not everyone did that and there were
no commit hooks to prevent the mess.

I wish there was a way to enforce the correct metadata in git, whether by
hooks or .gitattributes, so that the order is preserved once reached.
