Traditionally, [a-z] meant to match all characters in the range 'a'..'z' 
when using native encoding. Long ago some folks tried to change that so 
that it instead matched all characters collating between 'a' and 'z' 
inclusive, and glibc and some other libraries implemented things that 
way. This is now widely viewed to be a mistake, and POSIX now takes no 
position on the mess (implementations can do whatever they like).

Gnulib attempts to take the traditional meaning (though it doesn't 
always succeed, I expect). When we have time we are trying to move 
Gnulib and Glibc back to the original meaning. Code fixes to that effect 
would be welcome (both in Gnulib and in Glibc, I expect).
