>Not to mention that coding style may require that function calls broken to 2 lines must have the arguments aligned at the opening parenthesis. That doesn't result in any problems with using <TAB>s, unless the coding style also requires you to replace all (leading) sequences of N spaces with with a <TAB>, which is, IMO, quite brain-dead. For example, if (cond) { <TAB>foo(1, <TAB><SP><SP><SP><SP>2); } looks fine regardless of the width of <TAB>. Admittedly, your first problem remains; a problem with dumb editors. In truth, your editor could well signal if your lines exceed the limit (indent-width*indent + rest) you have set for your project, just as easily as it can draw a line at a column. The harder problem is that you need a context-aware editor for it to help you with indenting. Most editors are incapable of that by default.
