slapcat generate extra "space" characters in LDIF output

[Frank Bonnet <f.bonnet@esiee.fr>]

Hello

I'm in trouble with slapcat when generating a LDIF file
it puts some extra "space" characters into some dn longer than 80 
characters.

is there a way to change the output format of slapcat command
to generate lines longer than 80 characters in the LDIF file ?

I need this because I need to duplicate our directory server
to another TLD and I need to substitute

dc=fr by dc=biz

but sometime I get   this

------------------------------------------------dc=fr

sometime I get this

------------------------------------------------dc=
 fr

sometime I get this

------------------------------------------------dc
 =fr

sometime I get this

------------------------------------------------dc=
 fr

Thank you
