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).

@@ -19,6 +19,20 @@ The **reindex** command searches for all messages matching the
supplied search terms, and re-creates the full-text index on these
messages using the supplied options.
+Supported options for **reindex** include
+
+ ``--try-decrypt=(true|false)``
+
+ If true, when encountering an encrypted message, try to
+ decrypt it while reindexing. If decryption is successful,
+ index the cleartext itself. Be aware that the index is likely
