In some environments (typically, buildbots), this variable may not be available. This can cause tests to behave differently. Explicitly set the variable to "vt100" to ensure consistent test behavior. It should not matter that we do not inherit the process TERM variable, as the child process runs in a new virtual terminal anyway.
