Hello,

I reviewed and applied all of your three patches.  I fixed minor
formatting and typing of C language issues.  Pushed.

Besides,

I changed log_fatal into log_error, so that dirmngr_exit will be
called, and the message is not required to be translated, just like
the one of gpg-agent.c.

If these messages are needed to be translated, let us do that in
another change consistently, so that we can minimize translators'
work.
