Ah, no it doesn't.
    
    MvL> unicodeobject.c does use tabs for indenting multiple levels.

C-x h
M-x untabify RET

    MvL> In my revised patch for unicodedata.c, I put just

    | /* 
    | Local variables:
    | c-basic-offset: 4
    | End:
    | */

+1

Dang.

BTW, for the Emacsen in the audience, here's a little elisp I use to
normalize whitespace.  I mostly use this in Python code so YMMV.  It
frst untabifies the buffer, and then it deletes bogus trailing
whitespace.  I think it mostly works. ;)  The defalias is just because
I can never remember what I called the function and don't have it
bound to a keychord.
