Common length is 3 on x86, and as said we use 8. > That said if you still feel strongly about this then I am not strongly > opposed to adding an 8-space column alignment. I certainly think it helps readability a lot. 8 also matches the common use (fair parts of gas'es testsuite, Linux) of hard tabs. Jan
