Subject: 29.0.60; c-ts-mode breaks with '"' separated macros

The following code is parsed wrong with c-ts-mode:

#include <gio/gio.h>

int
main (void)
{
   GFileInfo *info;
   GFile *file;

   file = g_file_new_for_path ("some/path");
   info = g_file_query_info (file,
                             G_FILE_ATTRIBUTE_THUMBNAIL_IS_VALID ","
                             G_FILE_ATTRIBUTE_THUMBNAILING_FAILED ","
                             G_FILE_ATTRIBUTE_TIME_MODIFIED ","
                             G_FILE_ATTRIBUTE_STANDARD_FAST_CONTENT_TYPE,
                             G_FILE_QUERY_INFO_NONE,
                             NULL, NULL);
}

c-ts-mode doesn't assume  G_FILE_ATTRIBUTE_THUMBNAIL_IS_VALID (and
others) to be a string (or some function/macro call that results in a
string) resulting in broken font locking and tab indentation.

The same code seems to work fine with c-mode
