I have to express healthy skepticism as to whether performance is *so*
critical that you can't just do:

str.gsub!(/((^|-).)/) { $1.upcase }

and if it is, then I'll express healthy skepticism as to whether or
not Ruby is the right language for the job :-)

I don't know of any C library that does the above, so if you need it,
you should probably go ahead and write it. You can base it off
rb_capitalize(_bang).
