Latest builtin-commit series

Hi,

I sent out a new builtin-commit patch series last night, and figured I
should have written a cover letter to describe the changes there.
Better late than never:

      * rebase to Pierres strbuf changes.  Note, there is still some
        strbuf tweaking required, to let stripspace work on a strbuf.
        Also, I changed the semantics of stripspace to always add a
        newline if the last line doesn't have one.  I believe the
        current odd semantics (always remove the last newline) comes
        from not being able to easily add a newline, but now that it's a
        strbuf, that's easy.

      * Fixing the last bug that caused trouble in the test suite: even
        if run_status says there's nothing to commit, proceed if we're
        doing a merge.

      * Set the test suite default editor to '/bin/true' instead of ':'.
        Since we're not exec'ing the editor from shell anymore, ':'
        won't work.  Maybe we should special case ':' in launch_editor
        or perhaps make launch_editor use system(3).  Not sure.

      * The first few patches are good to go, and if we can get them
        committed to next, we can focus on the builtin-commit patch.
        Specifically:

                0001-Enable-wt-status-output-to-a-given-FILE-pointer.patch
                0002-Enable-wt-status-to-run-against-non-standard-index-f.patch
                0003-Introduce-entry-point-for-launching-add-interactive.patch
                0004-Clean-up-stripspace-a-bit-use-strbuf-even-more.patch
                0005-Add-strbuf_read_file.patch
                0006-Export-rerere-and-launch_editor.patch
                        (edit our "and launch_editor" from the title)
                
        should all be fine and easy to review, whereas 
        
                0007-Implement-git-commit-as-a-builtin-command.patch
                
        will probably need some careful reviewing.  That said, it is
        feature complete, the code is nice enough and it passes the test
        suite.  It's just a very important part of git :)

cheers,
Kristian
