restored for directory a/b, but is restored for the other 4
directories in the archive.

tar is "tar (GNU tar) 1.15.1"
uname -a gives
"Linux Knoppix 2.6.12 #2 SMP Tue Aug 9 23:20:52 CEST 2005 i686 GNU/Linux"
Filesystem is ReiserFS on top of LVM2

---------- test.sh ----------
echo "- Original files"
mkdir -p a/b/e
mkdir -p a/b-c/e
touch -t 200001010000 a a/* a/*/*
find a | sort | xargs ls -ld

echo "- Archived files"
find a | sort | tar cf a.tar -T - --no-recursion
tar tvf a.tar

echo "- Extracted files"
rm -rf a
tar xf a.tar
find a | sort | xargs ls -ld
