--- Comment #1 from wbe@psr.com ---
/usr/bin/sort, with no options, is doing a case-independent sort.

Example: file foo containing:
1 Abcd 2
1 abcd 1
2 Abcd 1
2 abcd 2

with environment variables:
LANG=C
LC_CTYPE=iso_8859_1
MM_CHARSET=UTF-8
LC_ALL=en_US.ISO8859-1
LOCALE=C
in case any of those matter,
which I would think would sort exactly as is ('A' before 'a'), instead gets
sorted case-independently:

# sort foo
1 abcd 1
1 Abcd 2
2 Abcd 1
2 abcd 2

Unless I'm missing something, this looks wrong.
