Thanks for the bug report. While implementing the fix I learned .d could also refer to dtrace scripts so I added support for that too. Fix went in with svn commit 441; svn head is at
https://sourceforge.net/p/cloc/code/HEAD/tree/trunk/cloc
would be grateful if you'd test it out a bit.

Looks OK to me. No apparent issues while running on local checkouts of my code.
