Issue with interacting with the GPG card

[Manoj Srivastava]

Hi,

        I have been having an issue with interacting with GPG using the
 gnupg-agent when the key is on the FSF GPG card.  When using an emacs
 compiled from git master HEAD
 (commit5a0472e8ea9128f75bca04f5f65682ae8280c208) I am seeing a failure
 to load an gpg encrypted file. With an emacs compiled on February 8th
 it loads just fine.

        When I revert the gpg.conf to use a key that is on the file
 system (and not on the gpg card) both versions load the file fine, so
 this regression is only the interaction with the gpg card. I do use
 gpg2 and the gnupg-agent in either case.

        I have bisected the issue down the the following commit:

    Default to gpg2 instead of gpg
    
    * lisp/epg-config.el (epg-gpg-program): Prefer gpg2 over gpg, if
    it exists.  This fixes many problems with using the GPG
    authentication agent.

 Pardon me if it is rude to also communicate this to the development
 list.
