t7301: use test_terminal to check color

peff · gitster · commit 3c788e79b857 · 2017-10-04T11:49:31.000+09:00
This test wants to confirm that "clean -i" shows color
output. Using test_terminal gives us a more realistic
environment than "color.ui=always", and prepares us for the
behavior of "always" changing in a future patch.
