Try to decrypt any encrypted parts of newly-discovered messages while
re-indexing them. The cleartext of any successfully-decrypted
messages will be indexed, with tags applied in the same form as from
notmuch insert --try-decrypt=true.
Note: if the deprecated crypto.gpg_path configuration option is set to
anything other than "gpg", we ignore it (and print a warning on
stderr, if built against gmime < 3.0).

messages using the supplied options.
+Supported options for **reindex** include

+ ``--try-decrypt=(true|false)``
+
+ If true, when encountering an encrypted message, try to
