[PATCH v2 3/5] mailinfo: skip quoted CR on user's wish

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In previous change, we've turned on warning for quoted CR in base64
encoded email. Despite those warnings are usually helpful for our users,
they may expect quoted CR in their emails.

Let's give them an option to turn off the warning completely.

 DESCRIPTION
@@ -89,6 +89,22 @@ This can be enabled by default with the configuration option mailinfo.scissors.
 --no-scissors::
 	Ignore scissors lines. Useful for overriding mailinfo.scissors settings.
 
+--quoted-cr=<action>::
+	Action when processes email messages sent with base64 or
+	quoted-printable encoding, and the decoded lines end with CR-LF
+	instead of a simple LF.
++
+The valid actions are:
++
+--
+*	`nowarn`: Git will do nothing with this action.
+*	`warn`: Git will issue a warning for each message if such CR-LF is
+	found.
+--
++
+The default action could be set by configuration option `mailinfo.quotedCR`.
+If no such configuration option has been set, `warn` will be used.
+
 <msg>::
 	The commit log message extracted from e-mail, usually
 	except the title line which comes from e-mail Subject.
