Makefile syntax highlight bug, caused by comments #17

From @Leedehai on June 19, 2017 20:22

• VSCode Version: 1.13.1
• OS Version: macOS 10.12.5

Steps to Reproduce:
In this Makefile snippet, the variable "HCC_LIB_OBJ" in the second line is not properly colored, due to comment at the end of the first line. If the comment is removed, "HCC_LIB_OBJ" is colored correctly. But "HCC_LIB_OBJ"'s colorization should not be affected by whether there is a comment in the preceding line.
