2d42579886
Summary: This patch fixes a few problems with the FormatAnsiTerminalCodes function: * It does an infinite loop on an unknown color value. * It crashes when the color value is at the end of the string. * It deletes the first character behind the color token. Also added a few tests that reproduce those problems (and test some other corner cases).
