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

Make the construction of the code-completion string for a function
...
template smarter, by taking into account which function template
parameters are deducible from the call arguments. For example,
template<typename RandomAccessIterator>
void sort(RandomAccessIterator first, RandomAccessIterator last);
will have a code-completion string like
sort({RandomAccessIterator first}, {RandomAccessIterator last})
since the template argument for its template parameter is
deducible. On the other hand,
template<class X, class Y>
X* dyn_cast(Y *Val);
will have a code-completion string like
dyn_cast<{class X}>({Y *Val})
since the template type parameter X is not deducible from the function
call.
