proposed multiple recipients option (w/ patch)...

[Matthew Whitworth]

I have noticed that a lot of gnupg users have trouble getting multiple
recipients to work with the "-r, --recipient" option.  Specifically,
users of PINE need to resort to a gpg wrapper program to iterate
through the list of recipients and prepend the "-r" before each.

Would it make sense to add a specific multiple recipients option?  I
can see the value of specifying:

$ gpg -ea -R "recipient1 recipient2..."

rather than

$ gpg -ea -r recipient1 -r recipient2 -r ...

Here is a fairly simple patch for such an option using -R and/or
--recipients that has worked for me so far:

Thoughts?
