Added TC for typechanged status

[hallzy]

I came across "typechanged" the other day in my git status. It occurs when (for example) you change a file from being a regular file, to a symlink.

Not sure if you want this in. I am using "TC" in the terminal to show this.

I would also like a check on the grep's in the lines that I added. I understand that everything inside of the square brackets can be matched, but I am unsure what letters I would also need with this.
