Even better and imho more robust should be
fu! MaxLen()
return max(map(getline(1,"$"), 'strlen(matchstr(v:val, "^\\d\\+")')))
endfu
Otherwise, if you have long numbers in the first column, max() will always
return the wrong result, since its argument seems to overflow (max
argument seems to be 2^31).

Thanks John, I think that explains it.
