Failure to compile under clang 6.0

After looking at the code, the check doesn't make much sense. width() is generally gonna return a signed size_t value. It will never be larger than uint64_t. You could check to see if it's less than 0, but otherwise I'm not really sure what you are checking here.

I was trying to shut up Visual Studio in 32 bit mode wherestd::size_t is 32 bits, but w could potentially be larger, although in practice that makes no sense. It's now the usual dance to keep three compilers in different versions and in both 32 and 64 bit mode happy, all using extremely high warning levels... 🤔

I guess limiting the indention to 256 should be enough for any reasonable real-world use-case and it might even catch errors if someone really messed up and sets the width to, say, a million spaces or something... plus the code will be much clearer...
