I thought that two new face variables (e.g. `escape-glyph-face' and
`nobreak-space-face') would be useful to imitate buffer-local faces.
I guess users might want to use different faces for control characters
or nbsp in different buffers, or to set `escape-glyph-face' to the default
face to not highlight control characters in some buffers.
