When one wants to sort a file in which letters are just codes,
not meaningfull words, the sort order obtained through LC_COLLATE
is very often inadequate.
The help suggest to set LC_ALL="C", but this is often inadequate as well
in complcated shell scripts.
I attach a small patch, which adds a global command-line option: -A
and s sub-option for use in individual keys : a
These options force the same ordering as LC_ALL="C", without tempering
any environment variable.
Numeric sorts, monthes etc. are not modified.
I hope that it may be useful for others.
You are free to use the patch as you want.
