I can confirm this fixes the bug, I hope you can commit it soon.

It's very nice that if I cancel the encryption, I remain in the file.gpg
buffer, but it's unsaved.  If I try to save again, it brings up the save
dialog again.

If I open a symetrically encrypted file.gpg and write it to another
file1.gpg, I never get a question about the encryption.  EasyPG assumes
I want symmetric encryption again.  I don't know if that's a feature or
a bug.

Can the passphrase and symmetric encryption/key choice be automatically
cached for a whole directory of files, if it's entered for any one of
them?  That way I can have ~/Maildir-crypt/{cur,tmp,new} encrypted
consistently, for example.

In the key selection buffer, (described as "Major mode for
`epa-list-keys'") I think it would be nice to have

C-c C-c and Enter anywhere (except the "Cancel" button or on a key)
equivalent to "OK"

C-c C-k equivalent to "Cancel"

Thanks
