I'd note that while the current maximum width of lines is enforced to 76 chars, they happen to be 78 char long (because of an extra LDIF_KLUDGE set to 1 and, I guess, of the leading blank).
In any case, in the spirit of being liberal when needed, I have nothing against allowing OpenLDAP tools to visualize LDIF with arbitrary width, as soon as the default behavior remains the original one, in order to avoid breaking existing software.
