Writing

doesn't really make sense.

Actually, we could just make that an error.

    T2 tabs followed by S2 spaces, then it is an error if

I presume you mean not an error, just not the same indentation?

I mean an error - it indicates ambiguous use of TABs.

The following would break that rule, yet is not ambiguous:

@code{
_TAB_if (...) {
_TAB__TAB_foo(bar,
_TAB__TAB_    baz);
_TAB_}
_TAB_mumble(frotz,
_TAB_       blatz);
}

Were you assuming the lines were consecutive?
I think I could still find counter-examples.
 

... alternately just define a tab as 8 spaces.

That is fine in a Unix-based culture.  Some programming
cultures use TAB to mean "indentation unit", which can
be set according to user preference.

This was not meant seriously, but rather to throw out another
option showing how hairy this all gets.

However, if we can get consensus on the corner cases, making
some of them errors if need be, I'd be willing to support it.
