Bug 289543: ports-mgmt/pkg - pkg.conf(5) - CASE_SENSITIVE_MATCH has no effect
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=289543



--- Description ---
On 14.3-RELEASE, using pkg v. 2.3.1 and 'latest', I cannot use 
CASE_SENSITIVE_MATCH to set case sensitve matching; pkg.conf(5):
OPTIONS
       The following options can be defined in pkg.conf:
   [...]
   CASE_SENSITIVE_MATCH: boolean
		    Match package names or regular expressions	given  on  the
		    command line against values in the database in a case sen-
		    sitive way.  Default: NO.


For testing I used:
# pkg rquery -e '%n=gsed' '%o'
textproc/gsed

or rather 'Gsed' that is not present in the ports tree.

After changing CASE_SENSITIVE_MATCH to YES, I get:
[0-0] # date -u; uname -a; pkg -v

FreeBSD tm1 14.3-RELEASE-p2 FreeBSD 14.3-RELEASE-p2 GENERIC amd64
2.3.1
[1-0] # pkg -vv | grep CASE_SENSITIVE_MATCH
CASE_SENSITIVE_MATCH = true;
[2-0] # pkg search Gsed
gsed-4.9		       GNU stream editor

Expected:
[3-0] # pkg search Gsed
[4->1<] # echo $?
1

That is, expecting the same result as:
[3-0] # pkg search -C Gsed
[4->1<] # echo $?
1

The same problem occurs with 
   pkg-query
   pkg-rquery
