GPGDecrypt: Handle (un)encrypted files consistently

Browse Source 
In the refactor to use the *Cmd events, an unencrypted file was simply
:read into the buffer.  This incorrectly caused an extra blank line to
be added to the top of the buffer.

The handling of encrypted files properly handles this, as well as
triggering BufRead(Pre,Post) events.

Instead of returning early for unencrypted files, go through the same
steps as for encrypted files (minus the encryption specific steps), thus
preserving the content of the original file.
