With the patch, it is fixed, but:

I don't know, but with the patch the quotes around the string seem to
be stored literally, i.e. single quotes or double quotes, depending on
which were typed in. Will that not break saving in -mat format, if the
string was given with double quotes? I can not test, since saving
anonymous functions in -mat format does not work now anyway.
