Flagrant error on my part in not posting a proper test case. :)

I'm still baffled with what is happening to returns when this ends up
in a function:
function! Str_wrap(str, len)
return substitute(a:str, '\([[:print:]]\{,' . a:len .
\ '}\)\>[^[:cntrl:]]', '&\n', 'g')
endfunction
function! Version()
redir @x
silent! version
redir END
echo Str_wrap(@x, 70)
endfunction
call Version()
Tony's previous approach is a work-around, but I'm trying to write a
more generic substitution for wrapping.
