Golf - now for the Sentencing.

[grep]

Inspired by this node I thought a golf challenge of handling sentence case would be a lark.

Rules:

English sentences

must work on one or more sentences

capitalize the first word in a sentence

capitalize single I's

to keep it simple, only periods for ending punctuation

obviously proper names don't count

and to start it off

00000000011111111112222222222333333333344444444445
12345678901234567890123456789012345678901234567890
$_=join'. ',map{ucfirst}split/\. /,lc;s/\bi\b/I/g;

this is my first golf so hopefully I won't be too embarrassed with a score of 50
