So basically for the same reason make still cares about the difference between 0x20 and 0x09. Which honestly never made sense to me. I mean, we all know the story about how the original author realized having leading tabs, rather than leading whitespace, as a syntax element was a terrible idea. But I never understood why he couldn't modify make to accept the latter instead of the former -- more specifically, why "there's already an existing user base" was cited as a reason not to make this non-breaking change.
