What Seebs is refering to is that it is difficult or impossible to
re-indent Python source automatically after the indent structure has been
broken (such as his email being converted to html on the server or a web
forum without the possibility of <pre> or [code] tags).  When C becomes
so obfiscated, you can run it through indent to recover the structure of
the source to something that you are familiar with (I actually think macros
could cause problems; but, Seebs has already admitted weaknesses in the C
preprocessor.).  The same is not always true for Python where information
about the code structure may be destroyed.
