Dear maintainer!

I'm not positive that this is a bug (the man page for grep does warn about
character ranges in locales other than C) but it produces very surprising
results in grep.

Presumably this is realated to bugs #506784 and #511357.

% echo -n abcdefghijklmnopqrstuvwxyz| sed 's/./&\n/g'| LC_COLLATE=C grep '[a-z]' 
a
b
c
d

% echo -n abcdefghijklmnopqrstuvwxyz| sed 's/./&\n/g'| LC_COLLATE=sv_SE grep '[a-z]'

% : Note the lack of 'w' above.
% LC_COLLATE=sv_SE grep '[a-w]'                            
grep: Invalid range end
% : This time at least there was an error message to warn me about the problem.


As i typically write "[a-z]" as shorthand for "[[:lower:]]" when i don't
need to match any national characters this bothers me quite a bit.

The sv_SE locale got some rework in glibc 2.34, finally fixing this bug.
I am therefore closing it.
