This nearly works, but is doubling existing line breaks.
The application is this :version pretty-fier:
function! Str_wrap(str, len)
return substitute(a:str, '[[:print:]]\{,'.a:len.'}','&\n','g')
endfunction
function! Version()
redir @x
silent! version
redir END
" add some line breaks between major sections
let @x = substitute(@x, '\n\([+\-]arabic\)', '\n\n\1', '')
let @x = substitute(@x, '\n\(\s\+system\)', '\n\n\1', '')
let @x = substitute(@x, '\n\(Compilation\)', '\n\n\1', '')
let @x = substitute(@x, '\n\(Linking\)', '\n\n\1', '')
" wrap
echo Str_wrap(@x, 70)
endfunction
command! Version call Version()
