The below simply adds a buffer-local `subword-superiority' defcustom
which, when set, makes `subword-mode' treat symbol_words as a single
word.  I named it to reflect the opposite behavior (the opposite of
"sub" is usually "super", e.g. subscript vs. superscript).  Let me know
what you think and if you'd rather see a separate mode or even a
separate file instead.  IMO it's such a simple change that I'd rather
not make it a big deal.

The only possible enhancement I'd want over the attached is to also make
`subword-mode' override the CUA keyboard shortcuts (C-left, C-right),
but I wasn't sure if that's OK in general.
