Git says WARNING: terminal is not fully functional because of wrong TERM

When i run git log or git diff in IntelliJ terminal, i always get this message first:

WARNING: terminal is not fully functional
-  (press RETURN)

And i have to actually hit enter to see the result of the command.

I am on Win 8.1 x64 and using msysgit 1.9.5. When i ran git from cmd.exe, i do not see the same problem.
I already added set the TERM environment variable to msys, as this answers suggests.

The problem is that the IntelliJ terminal still uses a different value for TERM: xterm-256color.

Is there a way to change that?

Thanks in advance!
