[PATCH] Support encrypting for PGP keys without subkeys

[Amir Yalon]

The patch looks correct. It adds `pub` records, but not all of them, since field 12 (key capabilities) is filtered to include only keys with `e` (the encrypt capability). It is interesting to note that the filter on field 12 seems sufficient, which makes the filter on field 1 (type of record) redundant (though good for clarity of intent).
