[pass] [PATCH] reencrypt_path(): handle encrypting main pubkey

[Quentin Minster]

Hi there,

Attached is a small patch to handle the 'encrypt' capability on the main
public key instead of on a subkey, when assigning $gpg_keys in function
reencrypt_path().

The subkey case looks like this:
  sub:u:2048:1:2EE5CDCE9B368A49:1398223729::::::e::::::
The main pubkey case like this:
  pub:u:1024:1:BF619D0D554BAA78:1457908470:::u:::escaESCA:::::::

I've also attached a patch for the test suite, BUT it's only for
consistency (of the regexp) and does not actually test the encrypting
main pubkey case. This would need either adding a sixth test key or
replacing an existing key with 'encrypt' on the main pubkey.

Such a key can be created thusly (with GnuPG 2.1):
  gpg2 --batch --gen-key <<- EOF
	%no-protection
	%transient-key
	Key-Type: RSA
	Key-Length: 1024
	Name-Real: test-key
	Name-Comment: DO NOT USE
	Name-Email: test-key at example.org
	EOF

Please review, and tell me whether that's fit for inclusion or what I
can do to improve/fix it. :)

Thanks,
