mutt/mutt-1.5.11-wrapcolumn.diff

2005-05-09 12:27:44  Manfred Hollstein  <mh@novell.com>

        * globals.h (WrapColumn): Add new global variable.
        * init.h (MuttVars): Likewise.
        * init.c (mutt_init): Add warning message about deprecation of
        wrapmargin variable in favour of new wrapcolumn. Map uses of
        wrapmargin onto corresponding settings for wrapcolumn.
        * handler.c (text_enriched_handler): Initialize .WrapMargin field
        under consideration of the new variable WrapColumn.
        (text_plain_flowed_handler): Likewise for flowed_max.
        * pager.c (format_line): Likewise for wrap_cols.
        * Muttrc, doc/manual.sgml: Add documentation for new variable.
        * doc/manual*.html, doc/manual.txt, doc/muttrc.man: Regenerate.
