Several changes together in a murky mess:
...
1. Change some "\n" -> '\n'.
2. eliminte some std::string's by using raw_ostream::indent.
3. move a bunch of code out of the main arg parser routine into

4. Greatly simplify the implementation of getOptionPred, and make
it avoid splitting prefix options at = when that doesn't match
a non-prefix option.
