    Send imap keepalives for interactive filters. · 4350694b

    When viewing attachments externally with a (non-copiousoutput) mailcap
    entry missing %s, the command is invoked as a filter, with the
    attachment piped into stdin.  However, unlike a filter, the user
    interacts with the command, instead of just displaying the output in
    the pager.
    
    Just as with the mutt_system() command, Mutt needs to send imap
    keepalives to keep those connections from closing during the
    potentially extended invocation.
    
    Thanks to John Hawkinson for the bug report, and his suggested patch,
    which this commit is based upon.
