added an inline comment about the use of strncmp



================
Comment at: lib/Frontend/DependencyFile.cpp:279
+  if (DependencyFilter.size() &&
+      strncmp(Filename, DependencyFilter.c_str(), DependencyFilter.size()) == 0)
+    // Remove dependencies that are prefixed by the Filter string.
----------------
I wasn't sure about using strncmp to do the prefix comparison, but i checked around in the clang code and saw strncmp used in several places so I thought it would be acceptable.
