Thanks; that is very much deliberate and has been with us forever.

    git-diff/git-apply: make diff output a bit friendlier to GNU patch (part 2)
    
    Somebody was wondering on #git channel why a git generated diff
    does not apply with GNU patch when the filename contains a SP.
    It is because GNU patch expects to find TAB (and trailing timestamp)
    on ---/+++ (old_name and new_name) lines after the filenames.
    
    The "diff --git" output format was carefully designed to be
    compatible with GNU patch where it can, but whitespace
    characters were always a pain.
    
    This adds an extra TAB (but not trailing timestamp) to old_name
    and new_name lines of git-diff output when the filename has a SP
    in it.  An earlier patch updated git-apply to prepare for this.
