gpg script to remove passphrase from secret key

[Kai-Min Sung]

Nevermind, I think I figured it out.  Here's the command to use:

gpg --status-fd 1 --command-fd 0 --edit-key user at domain.com < input

and here's the input file:

---input start---
passwd
old_pass

Y
save
Y

---input end---

Replace the first blank line with a new passphrase if you want to
change the passphrase instead of removing it.

Cheers,
-Kai
