dump method for binary values

[Jim H. <ha...@us...>]

I would like to see the dump method for entries made smarter about binary
values of attributes.  Right now, it just dumps them as regular characters
which messes up terminal emulators if the wrong values come across.  the
ldapsearch command on Solaris shows a value of NOT ASCII for them, which
is much friendlier.
