When printing the binary representation of the converted shader, shaderc also prints a comment with the ascii readable characters for each line. For unprintable characters, it relies on isprint() to replace them with the '.' character. Under MSVC 2017, isprint() may incorrectly return true for the tab character. This patch adds a WAR to explicitly test for tabs, to make sure they get replaced with '.'.
