The problem with tabs, IMO, are the following:

  - don't look right in patches (notice the different alignment of
    indented lines versus lines without any):

-int foo(int bar) {
-	return bar;
-}

    versus (assuming 8 space indents):

-int foo(int bar) {
-        return bar;
-}

  - I have yet to see an editor properly do tab-for-indent with proper
    space-for-alignment without manual management:

	int my_long_function_name(int bar,
	                          int baz)
^__tab_^^_______spaces___________^

By the way, this is *wrong* because tabs now have a defined size (8
here) which defeats the only (tangible[1]) advantage they have:

	int my_long_function_name(int bar,
				  int baz)
^__tab_________________________^
