This is one that came of necessity!
with keep="the ..." and input:
"Grand army of the Republic", "the arts"
I want: "Grand Army of the Republic" and "The Arts"
"forceFirstLetter" only applies to the first character in the token, not to
each word.

As written, if the prefix matches, it assumes the word capitalization is
correct. For my input data, this is sufficient -- but it should problem do
something smarter.
So, if you index "McKeen, Mckeen, mckeen, MCKEEN and McKEEN", you would get:
"McKeen, Mckeen, Mckeen, Mckeen And McKEEN"
If "okPrefix" was treated as *the* capitalization for input where the lowercase
prefix matches "mck", it would give:
"McKeen, McKeen, McKeen, McKeen And McKeen"
