Because saying "include -l" sounds like you really need to have the
full, complete "-l" output, and then it turns out that you don't, which
makes me happy, because I hate the full "-l" output in dired buffers.

Perhaps the string should be more wishy-washy?  "must be a sort-of full
listing, like -l or the like"?  Too long, though.
