That's a good point I think.

If this is desired this could be implemented pretty easily I guess.
But this behavior can be accomplished with vimscript as well -
something like:
function! GuideCol(cols)
let columns = []
for col in split(a:cols, ',')
if col =~ '[-+]\d\+'
call insert(columns, str2nr(col) + &tw)
else
call insert(columns, col)
endif
endfor
exe 'set mc=' . join(columns, ',')
endfunction
com! -nargs=1 GuideColumn :call GuideCol(<f-args>)
Cheers,
Gregor
