FEATURE REQUEST: ls -- Document that LC_* variable affects sort order

[Jari Aalto]

Cf. http://bugs.debian.org/561458

    $ ls -1
    20-name-change+my.21-compile-fixes.dpatch
    20-name-change~my.21-compile-fixes.patch
    20-name-change=my.21-compile-fixes.patch
    address@hidden
    20-name-change.patch

According to ASCII table http://asciitable.com/ the items are not
presented in correct order. In ASCII, that would be:

    $ ls -1
    20-name-change+my.21-compile-fixes.dpatch
    20-name-change.patch
    20-name-change=my.21-compile-fixes.patch
    address@hidden
    20-name-change~my.21-compile-fixes.patch

SUGGESTION

The LC_* variables seem to affect the listing order, but this is not
mentioned in the manual page. Please add following paragraph, as seen in
sort(1), to read:

       *** 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.
