Jesper hit another problem, when trying to push to github:
" [...]

    error: object 188c0969e6a6bef20b6bee69c92c5f24bb550d79:invalid
author/committer line - missing space before email


Doing a git fsck, showed that two commits (from the same author) has
this issue.

    error in commit 188c0969e6a6bef20b6bee69c92c5f24bb550d79: invalid
author/committer line - missing space before email
    error in commit 7a7fcfbf6f091497bf9dd8881327a9e00769548d: invalid
author/committer line - missing space before email


Both contains the following author information:

    reenberg@mille:~/src/xmonad/XMonadContrib_git$ git show

    commit 188c0969e6a6bef20b6bee69c92c5f24bb550d79
    Author: <its.sec@gmx.net>

I guess this is a simple fix of just making sure to add a space during
the fast-import, if there is no author information, and i guess the same
goes if there is no email information."

The author email is missing a name in the darcs patches. We should
probably check the format for correctness 
on import/export and add a "UNKNOWN_AUTHOR" placeholder or something.
