#366 --options=.ctags doesn't work under Windows

[Vadim Zeitlin]

Running ctags -R --options=.ctags . fails with "No such file or directory" error under Windows (7 if it matters, but it probably doesn't). Renaming the file to have an(y) extension works, e.g. --options=ctags.conf is fine.

In universal-ctags the message is suppressed now.
