bug#17016: sort program question -- bug with program, or documentation or my misunderstanding

[Leslie S Satenstein]

Hi
My first posting.

I believe there is an omission in man pages for the sort in the Description 
area section.  One cannot successfully use -d or without including -f on the 
line. Refer to  man sort under Description
 -d, --dictionary-order
              consider only blanks and alphanumeric characters


I have the following lines in a file   (see below as justification)

I want a file sorted as straight ascii sort.  I  eventually developed the two 
alternate command lines shown below, for two different purposes.

The undocumented bug is the requirement for the    -f    to be specified in 
order to have the sort work in the first of the two ASCII examples shown below,
otherwise the leading blank is ignored.

The first sort did not work for me unless the -f is specified.  Nowhere in the 
man page does it stipulate that for -d option the -f must be specified.
That is the bug.
 
Did I not understand man  sort         or   info sort     (linux fedora 20)     
  ?

Here are the two command lines and some sample lines as justification for my 
posting. I wish to sort a file shown below within the === by the first column
The following is the demo script

#!/bin/bash
LC_ALL=C
# to sort in ascii sequence where line ABCabc comes before abc       use the 
following
sort  -f -k1d -t '|'  x                         -o ABCabc
# output will have lines with leading ABC text occurring before abc as per 
ascii table.
# The sort will not work if the -f is omitted.

# The undocumented requirement is the need to specify  the -f
#
# to sort folding the in folded ascii sequence, where lines with sequence 
ABCbac sorts as AaBbCc ... use the following
# This part of the man pages is correct.  Except we may specify the folding 
option in two ways

sort -t '|' -k1f  x                                  -o  AaBbCc
or the line with    sort -f -t '|' -k1 x        -o AaBbCc
  

Try the first command or varients without the -f  to sort in column 1 ascending 
sequence


Here is a text file, between the === to paste into VI   Save it as x . and try 
to get the sort against the lines 

NB, the leading blank for line 1 is to force the line to be first in the output

======

Trying different variations of the sort with the above file leads to some 
results that do not appear to me to be correct.
I have specified locale, and with some variants, locale appears to be ignored.  
The above file is as ASCII text, not utf8
