Subject: [PATCH 01/23] fix bug in the --ca-bundle param of passing -f to
 _readlink

When _readlink is called the -f param must not be passed. _readlink (with
leading underscore) is a wrapper around readlink (without leading
underscore). _readlink already passes -f to readlink, that's why it must
not be passed to _readlink.
