slapcat generate extra "space" characters in LDIF output

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
