The highlighting code is driven largely by mime-types.  What does your
server assign as the mime-type for .h files?  Does the file carry a
mime-type in its Subversion svn:mime-type property?

It appears that Pygments supports an option for declaring the tabs-to-spaces
value.  ViewVC is not using that option right now, though.

There's a section of code like this in lib/viewvc.py:

    try:
      lexer = get_lexer_for_mimetype(mime_type,
                                     encoding=encoding,
                                     stripnl=False)
    except ClassNotFound:
      try:
        lexer = get_lexer_for_filename(filename,
                                       encoding=encoding,
                                       stripnl=False)

Try tweaking those get_lexer_for_* calls to include a tabsize=4 parameter.
(I'd do this myself, but I'm not in a test-ready state at the moment.)  If
it works, let me know, and I'll built that into a ViewVC as a
user-configurable option so folks don't have to hack the source to get the
feature.
