Description

When testing "lfs find" with composite files, I found it returned the file which only matched any of the specified component options, but not all.
For example, if you run the following commands, you will see it return /mnt/lustre/testfile.

lfs setstripe -E 1M -c 2 -E 4M -c -1 -i 0 -E -1 /mnt/lustre/testfile
lfs find /mnt/lustre --component-start=-100M --component-end=+5M

It shouldn't return any file because there is no file whose start>100M and end<5M.
