Add tests to format-test.cc

[planet36]

Both format("{:#.0f}", 0.01) and format("{:#.0f}", 0.5) should return "0." (like std::ostringstream does), but they return "0" and "0..", respectively

Please add some tests to test-format.cc like the following:

EXPECT_EQ("0.", format("{:#.0f}", 0.01));
EXPECT_EQ("0.", format("{:#.0f}", 0.5));

Good catch, thanks! Fixed and added tests in c85efef.
