In some cases, uftrace fails to detect busybox less, so the color is broken.

I found that the problem happens because of the following busybox less.

$ readlink /usr/bin/less
/usr/lib64/busybox/usr/bin/less

The file /usr/lib64/busybox/usr/bin/less is a shell script.

$ cat /usr/lib64/busybox/usr/bin/less
#!/bin/busybox.nosuid
