It's still almost impossible to create a terminal window when a GnuPG
process created by 'call-process' needs a passphrase.

Doesn't work for me, I'm afraid.  GnuPG indicates that there was a
gpg-agent failure and falls back to normal mode, and gpg-agent prints
the following error message:

gpg-agent[4854]: command get_passphrase failed: assuan error

In addition, I'd like to use --keep-tty without --daemon; this should
make gpg-agent (or curses pinentry) much more robust. Otherwise
strange things may happen (two applications access the PTY at the same
time, reading).

BTW, gpg-agent is totally hosed with symmetric encryption (GnuPG
crashes because there's no key ID).  And unfortunately, symmetric
encryption is the prime GnuPG application for me these days.
