At least attr has the same problem and is going the same direction
[1]. Cool. (I actually thought the patch was in and evidence that this
kind of backward compatibility breaking was ok, turns out the patch
has stayed around for years)

Seeing that again, I see this in the proposed log message:

    Full pattern must be quoted. So 'pat"t"ern attr' will give exactly
    'pat"t"ern', not 'pattern'.

I cannot tell what it is trying to say.  The code suggests something
quite different, i.e. a line like this

	"pat\"t\"ern" attr

would tell us that a path that matches the pattern

	pat"t"ern

is given 'attr'.  

The log message may need to be cleaned up.  The update by that
commit to the documentation looks alright, thoguh.
