Rationale for gpgme using gnupg-2.0?

[Mark H Weaver]

Hi Ludovic,

What was the rationale for commit ae3bded, which downgraded the gnupg
version used by gpgme from gnupg-2.1 to gnupg-2.0?

My reading of gpgme's NEWS makes me suspect that gnupg-2.1.x is not only
supported, but likely to be a superior choice.  NEWS includes:

 * More precise error codes are returned if GnuPG >= 2.1.8 is used.
 * Fixed regression for GPGSM use with GnuPG < 2.1.

If there's a reason to stick with gnupg-2.0 for gpgme, it might be good
to add a comment to explain why.

What do you think?

      Mark
