Re: sort -b also ignores tabs

[Alfred M\. Szmidt]

   Perhaps it would be more clear to say "whitespace" instead. Or are
   there types of whitespace other than 'spaces, tabs and newlines',
   which do not get ignored?

I think the locale comes into play here too, so saying anything
specific would be wrong.  And what is the difference between `blank'
and `whitespace'?  I don't see it...
