RFC: bzr co --lightweight to exiting directory "." not possible

[Jari Aalto]

I'd like to propose that the checkout would be possible to the exiting
directory:

        cd /usr/share/emacs/site-lisp
        <lot of stuff already>
        bzr co --lightweight /the/central/emacs/dev/dir .
        bzr: ERROR: Target directory "." already exists.

I went through workaround:

        cd /usr/share/emacs/
        bzr co --lightweight /the/central/emacs/dev/dir temp
        mv temp/*  /usr/share/emacs/site-lisp
        rmdir temp

But this is unconevenient. I suggest

        allowing checkout to existing directories WHEN there is no .bzr
        directory already.

Bzr in use was 0.11/Debian.
