A simple fix, and it certainly doesn't break anything on my system.

But, but - the code there is somewhat obscure, using || for flow control.
How about using something like this instead?

       streamsize npad = os.width() <= 0  ? 0 :
                     (bitsetsize_type) os.width() <= b.size() ? 0 : os.width() - b.size();

or even:

       size_t npad = std::max(os.width(), 0);
       if ( b.size() < npad )
                  npad -= b.size();

Along the lines of "leaving the code cleaner than when you found it".

I didn't even notice that the expression was that complex. I'll take another look.

[ahmedcharles]

This should be easier to understand.

[mclow]

I like that much better. Thanks!
Do you want me to merge it, or will you?

[ahmedcharles]

I should probably create a merge point between develop and master first, just realized that there isn't one.

[mclow]

I'd appreciate that.

I also can't merge it since I don't have permissions.
