I understand that --help output needs to be relatively short,
nevertheless adding a short example will probably save lots of similar
questions on the mailing lists if the FAQ is correct in stating how
frequently this question is raised.
Original:
*** WARNING *** The locale specified by the environment affects sort
order. Set LC_ALL=C to get the traditional sort order that uses
native byte values.
Suggested change:
*** WARNING *** The locale specified by the environment affects sort
order. Assuming any given locale may cause unexpected or unportable
behavior. For example, the en_US locale is case-insensitive and
ignores spaces and punctuation, while the C locale uses native byte
values and does not ignore either punctuation or spaces. Set LC_ALL=C
before calling sort to get the traditional sort order. An example of
different sort orders in two different locales using default switch
values:
en_US locale sort order: C locale sort order:
100,0,San Diego 10,1,San Juan
10,1,San Juan 10,1,San Tomas
10,1,Santa Monica 10,1,Santa Monica
10,1,San Tomas 100,0,San Diego
102,0,Santa Cruz 102,0,Santa Cruz
