[root@vm4 flr]# lfs mirror delete --comp-id 65537 foo
lfs mirror delete delete: option -d is mutually exclusive with -s, -c, -o, -p, -I, -F and -E options
delete a mirror from a file.

I suppose it uses an error message from "lfs mirror split" but I (--comp-id) and -p should be allowed to be used both for "lfs mirror delete" and "lfs mirror split -d" according to their manpage.
(-p works and does not trigger the error)
