+Changes:
+
+  If you have customized GHC import-path like follows,
+
+    (setq ghc-flymake-check-includes '("dir1" "dir2"))
+
+  You may update your settings as follows.
+
+    (setq ghc-ghc-options '("-idir1" "-idir2"))
+
+    or
+
+    (setq ghc-ghc-options '("-idir1:dir2"))
+
+  Now, you can simply pass GHC options to ghc-mod check command.
