My quote was from the grep 2.22 description (grep 2.22-1 Debian
package). It seems that this has changed later:

  http://www.gnu.org/software/grep/manual/grep.html

which is different:

  Skip files whose name matches the pattern glob, using wildcard
  matching. When searching recursively, skip any subfile whose base
  name matches glob; the base name is the part after the last ‘/’.
  A pattern can use ‘*’, ‘?’, and ‘[’...‘]’ as wildcards, and \ to
  quote a wildcard or backslash character literally.

The documentation is still ambiguous. For the "main case", is this
the canonical name as returned by realpath?

By doing a difference for subfiles of a recursive search, this is
even worse!
