Subject: add CH_VIRTUAL to allow to specify when use virtual headers
X-Git-Tag: neomutt-20160404~13^2~23
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=326f7817d68abef65c511154e85c15587942cd16;p=neomutt

add CH_VIRTUAL to allow to specify when use virtual headers

For example don't add "Tags:" header to the message when copy the
message to another folder. The virtual headers make sense only when
we display the message to user.
