There are test cases that do different things depending on whether the 
CASE_INSENSITIVE_FS prerequisite is set. I think it was the intent to 
report whether it is set and not whether one or the other value of the 
(now unused) variable is used somewhere.

BTW, the message texts do not show which variant is taken (these are 
without your patch):

On Windows:

t>sh t0050-filesystem.sh
will test on a case insensitive filesystem
will test on a filesystem lacking symbolic links
ok 1 - detection of case insensitive filesystem during repo init
ok 2 - detection of filesystem w/o symlink support during repo init
ok 3 - setup case tests
ok 4 - rename (case change)
ok 5 - merge (case change)
not ok 6 - add (with different case) # TODO known breakage
ok 7 - setup unicode normalization tests
ok 8 - rename (silent unicode normalization)
ok 9 - merge (silent unicode normalization)
# still have 1 known breakage(s)
# passed all remaining 8 test(s)
1..9

On Linux:

t@master:1002> ./t0050-filesystem.sh
ok 1 - detection of case insensitive filesystem during repo init
ok 2 - detection of filesystem w/o symlink support during repo init
ok 3 - setup case tests
ok 4 - rename (case change)
ok 5 - merge (case change)
ok 6 # skip add (with different case) (missing CASE_INSENSITIVE_FS)
ok 7 - setup unicode normalization tests
ok 8 - rename (silent unicode normalization)
ok 9 - merge (silent unicode normalization)
# passed all 9 test(s)
1..9

I'd even argue that there should be messages on Linux, too.
