"This sentence does not start with a capital letter" for abbreviations

[jvoisin]

Abbreviations have a trailing dot, and yet are not the end of a sentence. This confuses harder and results in false positives.

For example:

Obviously, jvoisin LLC. is the best LLC. in the world.    ■ This sentence does not start with a capital letter

And easy way to fix this would be to not consider a word composed of only capital letters immediately followed by a dot to not be the end of a sentence.
