Set LANG to something other than "en_*" if you want to keep the original
design, quoted-printable encoding, instead of this repository's preference,
format=flowed. The patched mmime.c is best accompanied by adjustments in
your editor to ensure that trailing whitespace is in the right place. For
example, in ~/.vimrc:
function! FixIndented()
" remove spaces at end of indented lines
silent! %s/^\s.*\zs \+$//
endfunction
function! TextFlowed()
setl tw=72
setl fo+=w
setl nojs
setl nosmartindent
setl list
set listchars=trail:•
endfunction
autocmd BufRead,BufNewFile */sent/cur/* call TextFlowed()
autocmd BufRead,BufWritePre */sent/cur/* call FixIndented()
