export hide-sensitive

What is determined as "sensitive" when doing an export with hide-sensitive ?

It appears pptp-client passwords aren't very sensitive.

[admin@router007] > /interface pptp-client export hide-sensitive

software id = ZZZZ-SSSS

/interface pptp-client
add allow=mschap2 connect-to=xxx.xxx.xxx.xxx name=pptp-007 password="notverysecret_l^gX0bs%jAlq]" user=pptp-007

Thanks for the report, I will check !
