No. I didn't say use only tabs. I said "use tabs only ***for leading
indent***". The distinction is very important. To align end of line
comments within a block, you use spaces. Not only does using space for
leading indent waste an excessive amount of space in source files with
relatively short lines and high levels of indent, it also forces
everyone viewing the file to use the indent level preferred by the
original author.
