extra::terminfo testing needs to be more thorough and especially we need to distribute some terminfo entries in src/test and verify that all the expected capabilities are there and their correct values.

I have planned to write up a tiny test shell in rust with this lib.

If I am able to write a shell with good test. I could try to make some improvement to the term lib.

I will try to work on it in the month.
