Patch Level: 0
Release Status: release

Description:
        Pattern matching is only sometimes case-(in)sensitive in character 
classes.

        (Which should it be?  The documentation - "any character that sorts 
between
        those two characters ['a' and 'b' for '[a-b]'], inclusive, using the 
current
        locale's collating sequence and character set, is matched." - is 
somewhat
        difficult to understand.)

        For example, [a-b] will not match B, but [b-c] will.

Repeat-By:
        touch B
        ls [a-b] #Yields "ls: [a-b]: No such file or directory"
        ls [b-c] #Yields "B"
