Oh I don't use layout, so this makes no difference to me. My blocks are
explicitly and unambiguously marked with braces, and my declarations
separated with semicolons. And my tabs are set to four, because the code
looks nicer that way.
And now with internationalisation, we're having all this trouble because
the "column number" notion necessary for layout just doesn't work very
well with such things as multiple scripts, special halfwidth forms,
composed vs. decomposed characters, different-sized spaces etc. I think
in this case some simple "90%" solution will be adequate, but my own
preference is to avoid it altogether.
