dovecot - Mar 2014 - Patch & feature request: hide passwords in doveconf -n by default

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

Hi,

attached patch tries to hide any setting that ends in _password (singular) 
in the output of doveconf by default.

doveconf -n
- -> passwords replaced by "<hidden>"
to prevent information leak when submitting bug reports

doveconf -n -P
- -> passwords visible
when used by admins locally

doveconf -n -P -P
- -> setting itself is not shown
to even hide that a password is set in the config

Warning: doveconf is used by internal programs as well, maybe they won't 
after the patch. Timo should check out the idea.
The passwords are left alone currently, if one queries one setting and if 
the values are saved to environment.

Kind regards,

- --
