Perform charset conversion on text attachments when piping. (closes #3773) (see #3886)
When piping a text attachment, there is no reliable way to know the
charset used.
Vincent Lefèvre says:
It was decided in the past that when there is no information on the
charset in a transmission to an external command (e.g. as for mail
composing), texts are expected to be transmitted in the local
charset.
Add a MUTT_CHARSET flag to enable charset conversion on text
attachments for both when $attach_split is set and unset.
