Description:
        Pathname expansion of the type [A-Z] disregards the case of file names,
        but it does not do this under all circumstances (see below).

Repeat-By:

        Note that the third command returns "list.txt" which it should not do.
        Also note that "[K-L]*.txt" returns "list.txt", whereas "[L-M]*.txt"
        does not.

        -> export LANG=de_DE
        -> ls
        GEN.txt  GEX.txt  list.txt  PRO.txt  RES.txt  SAM.txt
        -> ls [A-Z]*.txt
        GEN.txt  GEX.txt  list.txt  PRO.txt  RES.txt  SAM.txt
        -> ls [L-M]*.txt
        ls: [L-M]*.txt: Datei oder Verzeichnis nicht gefunden
        -> ls [K-L]*.txt
        list.txt

        This has to do with sorting:

        -> export LC_COLLATE=C
        -> ls
        GEN.txt  GEX.txt  PRO.txt  RES.txt  SAM.txt  list.txt
        -> ls [A-Z]*.txt
        GEN.txt  GEX.txt  PRO.txt  RES.txt  SAM.txt
        -> ls [L-M]*.txt
        ls: [L-M]*.txt: Datei oder Verzeichnis nicht gefunden
        -> ls [K-L]*.txt
        ls: [K-L]*.txt: Datei oder Verzeichnis nicht gefunden
