Comment (by kevin8t8):

 I don't think the patch is quite right.  The COLUMNS is set across all of
 mutt, and affects all subsequent mailcap invocations (and all subsequent
 forked commands).

 When used on a copiousoutput entry for autoviewing, we want the width of
 MuttIndexWindow->cols, but for other invocations, we don't want this set
 (or if at all, to the value of COLS).

 If we want to go this route, we might want to modify autoview_handler()
 instead.  And/or, maybe use a different environment variable like
 MUTT_PAGER_COLS.
