I use this little hack to detect indentation in Python's C files:
(defun c-select-style ()
"Hack: Select the C style to use from buffer indentation."
(save-excursion
(if (re-search-forward "^\t" 3000 t)
(c-set-style "python")
(c-set-style "python-new"))))
(add-hook 'c-mode-hook 'c-select-style)
-- where "python" and "python-new" are two appropriate c-mode styles.

Thus spake the Lord: Thou shalt indent with four spaces. No more, no less.
Four shall be the number of spaces thou shalt indent, and the number of thy
indenting shall be four. Eight shalt thou not indent, nor either indent thou
two, excepting that thou then proceed to four. Tabs are right out.
