"I get up at 7 a.m. every day." fail

[thaikhac]

I get up at 7 a.m. every day.
return result ['0'=>'I get up at 7 a.m.', 'every day.'] The returned result is incorrect, this sentence does not need to be split

[scotteuser]

I think the basic criteria here to handle this in code is to join 2 splits when:

1. directly after a full stop is a letter a.m. (from your example it seems like this is fine)
2. if the subsequent word starts with lowercase word, assuming its a continuation of the previous sentence
