[bug-gawk] Gawk manual A.7: [a-dx-z] ... might be equivalent to [aBbCcdXxYyz]

[Hermann Peifer]

Arnold,

Isn't there something counter-intuitive, if not wrong with the given 
example?

[a-dx-z] -> [aBbCcdXxYyz]   # example in Gawk manual
[a-dx-z] -> [aBbCcDdxYyZz]  # what I would have expected

In the next para, it should also read "...matched all of the uppercase 
characters except ‘A’ and ‘X’ ! "

'D' and 'Z' would be outside the given range if the collate order was 
the opposite of the above:

[a-dx-z] -> [aAbBcCdxXyYz]

Regards, Hermann
